MIT Researchers Convert Lead to Solar Power

Researchers at MIT are recycling materials from discarded car batteries into long-lasting solar panels that provide emissions free power while keep lead out of landfills. The system was described in the journal Energy and Environmental Science and was co-authored by Angela M. Belcher and Paula T. Hammon along with graduate student Po-Yen Chen, and three others.

The system is based on a recent development in solar cells that makes use of a compound called perovskite — specifically, organolead halide perovskite — a technology that has rapidly progressed from initial experiments to a point where its efficiency is nearly competitive with that of other types of solar cells.

“It went from initial demonstrations to good efficiency in less than two years,” said Belcher, the W.M. Keck Professor of Energy at MIT. Already, perovskite-based photovoltaic cells have achieved power-conversion efficiency of more than 19 percent, which is close to that of many commercial silicon-based solar cells.

Initial descriptions of the perovskite technology identified its use of lead, whose production from raw ores can produce toxic residues, as a drawback. However by using recycled lead from old car batteries, the manufacturing process can instead be used to divert toxic material from landfills and reuse it in photovoltaic panels that could go on producing power for decades. In addition, because the perovskite photovoltaic material takes the form of a thin film just half a micrometer thick, the team’s analysis shows that the lead from a single car battery could produce enough solar panels to provide power for 30 households.

As an added advantage, the production of perovskite solar cells is a relatively simple and benign process. “It has the advantage of being a low-temperature process, and the number of steps is reduced” compared with the manufacture of conventional solar cells, Belcher explained.

Those factors will help to make it “easy to get to large scale cheaply,” added. Continue reading

Albion Community Power Funds Biogas Project

Albion Community Power logoAlbion Community Power (ACP) has funded the development of a small scale landfill gas engine in Docking, Norfolk (UK). The project will be developed in conjunction with ACP’s biogas partner AlphaGen Renewables who will oversee the installation and operation of a 50kW microgeneration landfill gas engine. The project will generate power from the landfill gas resource at the site under a 20 year agreement with Norfolk County Council. The Docking projects represents the first project with AlphaGen Renewables and the first Biogas project in the ACP portfolio.

Richard Tipping, Chairman of AlphaGen Renewables said, “We are delighted to be partnering with ACP on this project, which is set to deliver strong returns. Renewables such as biogas are playing a growing role in the UK’s energy production.”

ACP undertakes projects in biogas as well as projects incorporating wind, hydro and solar energy. The company is looking to build a portfolio of similar, high yielding, landfill projects going forward.

David Gudgin, Head of at Renewables at Albion Ventures added, “Biogas is an increasingly popular area of renewable energy and we are looking forward to working with AlphaGen both on this project and others in the future.”

Some Retiring Utility Plants Need No Replacement

According to Black & Veatch’s 8th annual Strategic Directions: U.S. Electric Industry report, many retiring nuclear and coal power plants may not need to be replaced on a megawatt-to-megawatt basis. With new technologies and distributed generation along with soft energy demand growth, utilities will be able to replace those retiring with ones that produce less energy.

“This year’s Strategic Directions: U.S. Electric Industry report finds many utilities at a crossroads,” said Dean Oskvig, president of Black & Veatch’s energy business. “The influx of new technologies, new energy sources and new generation approaches, create immense challenges and opportunities for utilities. What has not and will not change, however, is the mandate to deliver the ‘always on’ reliable electric service the
industry has provided for more than 100 years.”

modal-primary-driver-for-rate-increasesThe report found that the rise of distributed generation in particular creates unique challenges for utilities. The technology requires rapid changes to the power grid in order to integrate new assets and resources. Utilities must also be able to ramp up capacity to account for varying renewable energy output (aka wind doesn’t always blow, the sun doesn’t always shine). Where distributed generation reduces demand, utilities will have to revisit their current revenue structure in order to ensure continued reliable service.

John Chevrette, president of Black & Veatch’s management consulting business, noted, “Every kilowatt that is now being produced by a third party or a consumer is a kilowatt not being sold by the utility. At the same time, utilities still carry the burden of building, maintaining and operating the bulk of the power delivery system. Given the high cost of maintaining these assets, we expect to see more utilities making the case with regulators to adjust their business models.”

Based on data collected by industry professionals across the U.S., the report tracks utility leaders’ views on a range of major issues. Some key findings include:

  • Half of the respondents stated their company is planning to replace retiring coal and nuclear power plants with gas generation. Natural gas will also be used as backup power for renewable generation.
  • Nearly 60 percent of utilities are updating emergency response plans in order to improve resiliency to weather and unanticipated events.
  • Utilities are working to provide consumers with resources to better manage energy consumption. Almost one-third of utility respondents stated their organization is offering Home Area Network solutions, such as smart thermostats, to support demand response programs.
  • More than 60 percent of utility leaders believe DG will grow beyond its current 5 percent market share of U.S. power generation by 2020.

New Jersey Home to First Energy Resilience Bank

New Jersey has created what they term the first of its kind in the U.S. “Energy Resilience Bank” (ERB) to focus on energy resilience. The bank was created in response to the impacts of SuperStorm Sandy where over 8 million people lost electric power in the region – many for several days. The ERB will provide $200 million for municipalities to finance clean resilient power solutions. Projects could include those that “would ensure a highly reliable power supply to critical public facilities such as water and wastewater treatment plants, hospitals, shelters, emergency response centers and transit networks in the event the larger electrical grid fails.”

New Jersey Disaster Recovery Action PlanOn July 23, 2014, the New Jersey Board of Public Utilities approved a sub-recipient agreement with the New Jersey Economic Development Authority to work jointly in the establishment and operation of the ERB. The ERB would be financed through use of $200 million of New Jersey’s second Community Development Block Grant-Disaster Recovery (CDBG-DR) allocation. According to the Governor Christie’s announcement, “the ERB will support the development of distributed energy resources at critical facilities throughout the state …to minimize the potential for future major power outages and increase energy resiliency.”

Clean Energy Group’s President, Lewis Milford, applauded the creation of the ERB. “New Jersey has created a model for all states to finance resilient power projects, to protect against power outages during severe weather events. The ERB is an important way for states to finance projects like solar with energy storage in food banks, fire stations, wastewater treatment plants, and schools. It deserves to be a national infrastructure finance model for states around the country.”

The Clean Energy Group is working with states and communities to help deploy more resilient power projects, and the organization cites financing as a remaining a key stumbling block. The New Jersey approach through the new ERB is a model that all states should consider as they deal with increasing problems of severe weather and the power system, problems that are only growing worse, according to Clean Energy Group.

SheerWind Offers INVELOX for Wind Power

There is a new technology available for wind power generation: INVELOX system. The new concept for wind power generation was developed by SheerWind and uses multiple turbines in a row or series to produce greater electrical power output. In essence, the INVELOX system is a large funnel that captures, concentrates and accelerates wind before devlivering it to turbines located at ground level, according to the company.

The company explains that by placing two turbines ina series, power increased by 1.7 times when compared to a single turbine. For example, one 1,000 kilowatt turbine-generator system in an INVELOX produces electrical energy for 341 homes, and two turbines operating in succession produces enough electricity to power 579 average sized homes.

“Because the INVELOX system directs and controls wind, we are able for the first time in history, to place multiple turbines together to produce more energy. This means a single INVELOX tower is able to increase its output— reducing cost per kilowatt— all without additional structure or land use,” said Cyndi Lesher, President of SheerWind “Increasing the ability to operate in areas never before feasible or economical with even less environmental impact.”

In addition, the company explains that because there are multiple turbines in a single INVELOX tower there is nearly no operational downtime because maintenance can be done on one turbine while the other continues energy production. With INVELOX, turbines are installed safely and conveniently at ground level, making maintenance less costly, safer and more efficient, according to SheerWind.

Martifer Solar Completes Ukraine PV Project

Martifer Solar has completed a 8 MW solar power project in the Vinnytsia region of Ukraine. The project, known as Shargood, was developed during what the company said was amid complex political and economic events that occurred in the country. The Shargorod plant is located less than 300 km southwest of Kyiv in the Vinnytsia Oblast of Ukraine.

Martifer Solar completed the 8 MW PV plant on an area of approximately 160,000 m2, using 33,000 modules installed on fixed structures. The Shargorod plant is expected to produce an estimated 9.2 GWh/year. With Martifer Solar Ukraine Shargorod Solar Project.jpgthis production capacity, the project will offset 3,855 tons of carbon dioxide on an annual basis, which is sufficient energy to power more than 11,000 inhabitants in the Vinnytsia region per year.

“This new 8 MW plant is a significant achievement for the team as it strongly displays our company’s ability to adapt and manage complex projects under extreme conditions. In addition, this PV project is one of the first of its magnitude to satisfy the current local-content requirements in place within the country,” said Francisco Queirós, country manager for Martifer Solar in Ukraine. “We are proud to work closely in our partnership with Rengy Development to maximize the potential for solar development of the Ukrainian market.”

This new PV project is the sixth project which Martifer Solar has built in Ukraine for Rengy Development. In total, Martifer Solar now has a total portfolio of 29 MW of utility-scale PV implemented in the country dating back to August 2012.

Narek Harutyunyan, managing director of Rengy Development said of the new solar project, “As we maintain our investment and development of solar projects in Ukraine, we continue to rely on the strength and proven talent of Martifer Solar as a partner in the market. We have shared several success stories in the Ukrainian market and this 8 MW plant surpassed our expectations given the current situation in the country.”

Kyocera Celebrates Tailand Solar Farm Completion

SPCG Public Company Limited and Kyocera Corporation have begun full operational launch of one of Southeast Asia’s largest solar power projects. Since 2010, 35 “solar farms” totaling approximately 257 megawatts (MW) have been constructed under the project, and connected to the utility grid in Northeastern Thailand. A ceremony held earlier this month in Surin Province commemorated the launch of the installations.

The project has an annual power output of approximately 345,000,000kWh — equal to the annual electrical consumption of approximately 287,500 Thai households. The power generated from the solar farms will be supplied to the Provincial Electricity Authority of Thailand (PEA).

7.46MW Solar Power Plant in Korat Thailand 2 Photo-Kyocera“Drawing from our four decades of experience in the solar industry, Kyocera has delivered high-quality solar modules which will generate clean, renewable energy for many years to come,” said Mr. Nobuo Kitamura, Senior Executive Officer and General Manager of the Corporate Solar Energy Group at Kyocera Corporation. “Kyocera is honored to have taken part in this project, which we believe is an important milestone for the development of solar energy in Thailand.”

Kyocera notes that Thailand’s rapidly expanding economy has brought rising concerns regarding the national power supply in recent years, alongside growing awareness of the need to reduce dependence on gas imports. In order to diversify its energy portfolio, a feed-in-tariff system for renewable energy sources was adopted in 2007. In response to the resulting strong demand for renewable energy, SPCG began the solar farm project in 2009 to construct and operate multiple solar power plants in Thailand. Kyocera was chosen to supply the necessary solar modules, totaling approximately 1,100,000 panels for all sites. The 35th solar farm was completed and connected to the utility grid in June 2014.

Wandee Khunchornyakong, CEO of SPCG Public Company Limited said of the project, “SPCG is very proud to be a pioneer of solar farm development in Thailand and the ASEAN community. SPCG is confident that our success will be an aid to future generations,” said “We are highly honored to be able to achieve this together with Kyocera, our long-term partner, with whom we shared the same philosophy, vision, and determination to develop one of the best solar projects in the world.”

The companies hope that the newly launched solar farms will reinforce the region’s power supply. They remain committed to promoting solar energy as a means to attain a low-carbon society.

Green Charge Networks Closes $56M Capital Raise

Green Charge Networks has closed a $56 million capital raise. K Road DG is providing funding and strategic management services to the company to enable them to accelerate deployment of GreenStation, under Green Charge’s Power Efficiency Agreement (PEASM). According to the company, the funding round is the largest amount of capital raised by any company in the intelligent energy storage space.

Green Charge offers an energy storage product that they say is proven to reduce power demand charges for commercial and industrial customers on their monthly utility bills. Green Charge’s GreenStation has been successfully installed by 7-Eleven, Walgreens, UPS, school campuses, and cities across New York and California. Now with the PEASM, Green Charge will own and operate energy storage assets deployed at customer sites, while providing the customer with a powerful combination of utility bill savings, zero capital and maintenance costs, and mitigated performance risk.

GCN_Stacked_Logo“Power efficiency is the next frontier in energy savings,” said Vic Shao, CEO at Green Charge. “We plan to leverage the alliance and financing from K Road DG to scale our company’s deployments and continue our customer-centric innovations.”

Green Charge Network explains that similar to a solar Power Purchase Agreement (PPA), the PEASM shifts the performance burden onto Green Charge as the asset owner instead of the customer. This type of financing model was key to spreading distributed solar around the globe, but has not been available in the energy storage market until now. This financing allows Green Charge to serve the broadest cross-section of the market.

“We are excited to enter into this strategic alliance and to provide growth capital that will drive deployment of Green Charge’s innovative technology to C&I customers on a commercial scale,” added William Kriegel, CEO of K Road DG. “K Road DG believes that Green Charge’s technology solutions respond directly to a global demand for intelligent energy storage.”

Market research firm IHS predicts that the energy storage market is expected to grow to an annual installation rate of over 40 GW by 2022 — from only 0.34 GW in 2012 and 2013.

Rwanda Set to Commission Solar Plant

The first utility-scale solar PV power plant is set to go online in early August 2014 in East Africa. The 8.5 MWp solar farm will be commissioned by the Government of Rwanda and is currently in its testing phase. Today less than one in five households in Rwanda have access to electricity. The new solar project will increase the country’s production capacity by up to 8 percent.

rwanda state flagIn early July, Rwanda’s Minister of Infrastructure, Prof. Silas Lwakabamba led a high-level delegation which visited the Gigawatt Global Rwanda Ltd construction site, the utility-scale solar power plant located near Agahozo-Shalom Youth Village (ASYV) in Rwamagana District, eastern Rwanda.

“Generation and provision of electricity to all Rwandans is a priority for the Government of Rwanda. This initiative to produce 8.5 megawatts of clean energy is an important addition towards closing Rwanda’s current energy gap,” said the Minister at the site.

The Norwegian company Scatec Solar is the Engineering, Procurement and Construction (EPC) company responsible for building the power plant, and Remote Partners is the local management and support firm. The project has been funded by Norfund (Norwegian Investment Fund for Developing Countries) and KLP. The Dutch company Gigwatt Global is the developer of the project. Once the plant is online, Scatec Solar will operate and maintain the plant which will feed electricity directly into the national grid. The price is lower than for electricity generated by diesel oil.

The Government is encouraging private sector involvement and private-public partnerships as part of its development policy. In addition, energy for all is an important goal in the fight against poverty. Energy must be affordable, energy supplies must be reliable, and last but not least, energy is ideally clean and renewable. Solar energy is an important part of the energy mix along with hydropower and other sources of renewable energy in Africa.

Panasonic Corp Installs Power Supply Container

powercontainer_Karimun0012Panasonic Corporation has developed an interesting offshoot of solar energy: Power Supply Container. The stand-alone photovoltaic power package was installed for the National Elementary School Karimunjawa 01 in Karimunjawa Island, Jepara District, Central Jawa Province, Indonesia. The Power Supply Container is equipped with 12 Panasonic “HIT(R)240” solar modules that the company said has high conversion efficiency and can generate approximately 3 kW of electricity. It can also provide stored power from 24 built-in lead-acid storage batteries (17.2 kWh as total).

Karimunjawa is an area where electricity is available at night using diesel generators. However, in the daytime these generators are stopped and no electricity can be used by the residents of the village. As no power for the village during the daytime interferes with administrative and commercial activities, improvement of the educational environment had been the top priority for the island. To solve this social issue, Koperasi Pundih Artah, which received Grant Assistance for Grassroots Human Security, Institute of Business and Economic Democracy Foundation (IBEKA) and Panasonic launched a project for improving the educational environment, by supplying and installing the Power Supply Container, under the cooperation of Jepara District and the Embassy of Japan in Indonesia.

To celebrate the introduction of “daytime electricity” a handover ceremony was held with Koperasi Pundih Artah and IBEKA. Now, during school hours, children can use LED lighting fixtures, ceiling fans and audiovisual educational materials using PCs and TVs. When there are no classes, the electricity is sold to nearby areas through a management association of the Power Supply Container topowercontainer_Karimun0017 contribute to activation of the regional community and improve the regional electricity infrastructure.

IBEKA is giving support for establishing management associations in Karimunjawa for independent operation of power supplies as well as provides training and supports for their operation, management and maintenance to achieve a sustainable power supply in Karimunjawa. Panasonic will continue to work with groups in Indonesia to bring more Power Supply Containers to areas without reliable electricity.

Himark BioGas to Build 3 Anaerobic Digestion Plants

Himark BioGas International is building three integrated anaerobic digestion (AD) and fertilizer plants for NEO Energy in Massachusetts and Rhode Island. The AD plants will be designed and constructed by Himark and will recycle food waste to produce renewable electricity and organic-based fertilizer. As part of the agreement, Himark BioGas will act as a technology licensor and owner’s representative on behalf of NEO Energy LLC during the design, construction and operation stages of the plants.

GPHH_webreadyShane Chrapko, CEO of Himark BioGas, said, “The development of the anaerobic digestion plants will positively contribute to effective food waste recycling, profitable pathogen-free fertilizer production, energy self-sufficiency and a reduction in carbon emissions for the local communities. Each ton of food waste diverted from the landfill will reduce Greenhouse Gas Emissions by just over one ton of CO2 (Equivalent).”

The AD plants will be designed based on Himark BioGas’ patented “IMUS” technology that can produce renewable energy and pathogen-free fertilizer from food waste, source separated organic materials, cow manure, ethanol plant waste/thin stillage, slaughter house waste, food processing waste and agricultural waste (open pen feedlot, sand-laden dairies, etc.). The IMUS technology also can handle feedstock containing large amounts of sand, dirt, rocks, plastic and cellulose. Furthermore, Himark said with its turnkey, guaranteed-maximum capital cost designs, the company guarantees electricity, gas and fertilizer outputs with any kind of feedstock.

“NEO’s anaerobic digestion plants will recycle food waste generated by supermarkets, food processors, restaurants and other institutions and divert that waste away from landfills and incineration facilities,” said Robert Nicholson, president of NEO Energy. “Our plants produce a high-quality organic-based fertilizer while reducing greenhouse gases, preserving landfill capacity and producing renewable energy. Our first plants will also be available to those businesses that will need to comply with the 2014 commercial food waste disposal ban in Massachusetts and the recently enacted law in Rhode Island requiring that food residuals produced by large waste generators be recycled starting in 2016.

Southern Nevada Water Authority Goes Solar

Southern Nevada Water Authority (SNWA) is going solar with the help of SunEdison. SNWA has signed a power purchase agreement that locks in the majority of its energy costs at a fixed rate. The power will be provided by a 14 MW solar farm that SunEdison will develop, construct, own and operate located in Clark County, Nevada.

SNWA logo“This partnership with SunEdison expands our renewable energy portfolio to about 18 percent of our total power mix, and it provides additional stability to power costs, which ultimately benefits Southern Nevada’s municipal water users,” said John Entsminger, Southern Nevada Water Authority General Manager. “When compared with traditional power production from fossil fuels, this solar facility will also save more than 100 million gallons of water and contribute to the sustainability of our community.”

According to SNWA, water is used in a number of ways in fossil fuel based electricity production, including generating steam to turn turbines, helping to keep power plants cool, and flushing away the fuel residue after fossil fuels are burned. By contrast, solar PV power plants do not use water in the production of electricity.

SunEdison-Logo“This project is a great example of how SunEdison can provide cost effective solar solutions to fit almost any location,” said Bob Powell, President, North America at SunEdison. “This ground-mounted facility will be built around a transmission and pipeline infrastructure that is quite complex – if we can do it here, we can do it anywhere.”

Construction of the facility will begin in early 2015 with commercial operation slated for later that year. Once operational, the solar power plant will be managed by the SunEdison Renewable Operation Center (ROC), which provides global 24/7 asset management, monitoring and reporting services. Data collected from the ROC is used to continuously improve the company’s products, project designs and service offerings.

Maine Utilities Partner to Improve Grid

Emera Maine and Central Maine Power (CMP) have agreed to jointly develop electric transmission projects in Maine. The goal of all projects is to improve links between southern New England and northern Maine, where more than 2,100 megawatts of wind power development have been proposed. The agreement between the utilities comes in response to a call by the six New England governors for investments in the region’s energy infrastructure to diversify the energy portfolio and gain access to new renewable energy resources.

As the state’s two largest utilities, the companies serve more than 95 percent of Maine’s homes and businesses. The utilities have significant expertise with transmission projects, including the MEPCO transmission line that extends from central Maine to New Brunswick, Canada.

Transmission Project in MaineCentral Maine Power is the state’s largest utility serving 605,000 homes and businesses in the southern third of the state. The company is nearing completion of the Maine Power Reliability Program, a $1.4 billion investment in new transmission lines and substations to reinforce its 345,000 volt bulk power grid.

“Our Maine Power Reliability Program is the largest construction project ever in Maine, and one of New England’s largest transmission projects,” said Sara Burns, president and CEO of Central Maine Power. “It’s a vast and complex undertaking, but four years into construction, the project is on time and on budget.”

Emera Maine serves approximately 154,000 homes and businesses in eastern and northern Maine. Significant transmission projects completed by Emera Maine include the 43-mile, 115,000 volt Downeast Reliability Project, and the 85-mile, 345,000 volt Northeast Reliability Interconnect in 2007.

“Electric transmission can be a significant challenge to new low/no emitting generation sources seeking to enter our New England market”, said Gerard Chasse, president and COO of Emera Maine. “That’s a challenge that our companies have been working together on for some time, particularly in Northern Maine. With this MOU we are renewing and expanding these efforts to identify and develop creative and cost effective transmission solutions to benefit the State and the region.”

The partners have outlined two initial phases of work. Phase One will analyze the feasibility of each project, including technical feasibility, public policy, regulatory considerations, and outreach to other potential parties to the project. Phase Two will include all development activities from design, engineering, siting, through construction bidding.

ACORE Study: Evolving Business Models for Renewable Energy

A new study has been released, “Evolving Business Models for Renewable Energy,” from the American Council on Renewable Energy (ACORE). With aid from several members, the report explores key issues and provides recommendations related to evolving utility and other business models for renewable energy. The report was produced in conjunction with ACORE’s Power Generation and Infrastructure Initiative.

“From potential storage benefits of electric vehicles, to recommendations on ideal scenarios for integration of distributed renewable assets, ACORE and its members are tackling the cutting edge issues facing our electricity sector today,” said co-author and CEO of American Clean Energy, Steve Morgan.

ACORE Evolving Biz Models for Renewable Energy.jogThe report details how distributed generation, smart grids, and microgrids are changing traditional utility business models, suggests outcomes for the successful integration of renewable energy at scale, and spotlights ways in which emerging energy sources such as concentrated solar power (CSP) and electric vehicles (EVs) are changing the way utilities look at generation, integration and storage.

“Our Power Generation and Infrastructure Initiative has always focused on solutions over politics,” said ACORE CEO Michael Brower, “and by convening our members who are developers, legal experts, sector analysts and financiers to review the business landscape, we guarantee a highly credible, critical and realistic view to help craft solutions for a cleaner, more reliable power sector future.”

Sections of the report include “Renewable Energy Drivers of Change,” “Overview of Actions from the Utility Perspective,” as well as “Distributed Energy: Understanding and Mitigating Commercial and Regulatory Risks”. These chapters are designed to build on the organization’s efforts to create bridges between the utility industry and renewable energy industry.

ACORE’s Power Generation & Infrastructure lead James Hewett called this focus “essential” noting, “The utility sector is well aware of the disruptive nature of distributed renewable energy. ACORE is focused on making this disruption an opportunity for utilities, not a threat. Frankly, it’s essential to the success of all.”

Sierra Club Launches Wind Energy Jobs Ad Campaign

With uncertainty around the major federal wind incentive, the Sierra Club has launched a national ad campaign urging Congress to reauthorize the critical incentive for domestic wind energy investments. The campaign focuses on Members of Congress with wind manufacturing jobs in their districts and states that are at risk of the Wind Production Tax Credit is not renewed.

The first wave of ads targets 20 House members who have been silent as the Wind Production Tax Credit has expired, and involves a television advertisement targeting Congressman Tim Walberg (MI-07) as well as geo-targeted online ad buys in 20 other districts. These members represent districts and states with a growing wind industry who have not taken a position in support of extending the federal Production Tax Credit for Renewable Energy. In most cases, they have taken no position at all.

The Wind Production Tax Credit expired at the end of last year, in part, said the Sierra Club, because of new opposition from groups backed by the billionaire Koch Brothers and other dirty fuels interests who’ve also fought to preserve the $4 billion in annual tax breaks for the oil and gas industry.

“The Wind Production Tax credit is arguably one of the best bets we’ve made on clean, domestic energy,” said Dave Hamilton, Director of Clean Energy for Sierra Club’s Beyond Coal campaign. “It encourages huge investments, creates good American jobs, helps our country become more energy independent, and cuts air and water pollution. But many in Congress are failing to act, leaving thousands of American workers and communities across the country blowing in the wind.”

The wind industry employs more than 80,000 American workers and produces enough clean energy to power 15 million homes. It saves more than 30 billion gallons of fresh water each year compared with other energy sources. According to the American Wind Energy Association, if growth remains steady, the industry will produce 20 percent of America’s electricity by 2030. Continue reading
