Ormat to Expand Kenya Olkaria III Geothermal Plant

Ormat - Kenya Geothermal PlantOrmat Technologies has announced they are expanding their Oklaria geothermal energy complex located in Kenya. The company has signed an amended and restated Power Purchase Agreement (PPA) with Kenya Power and Lighting Company Limited (KPLC).

Under the terms of the agreement, Ormat expects to increase the generating capacity of the complex by 24 MW, bringing the complex’s total capacity to 134 MW. The fourth plant is expected to come on line in the second half of 2016 and to sell electricity under a 20 year PPA with KPLC.

“Ormat’s Olkaria geothermal complex provides clean, reliable and firm power to over 200,000 Kenyan households, increasing the complex by an additional 24 MW will further benefit the Kenyan people,” said Ormat CEO Isaac Angel. “We see Kenya, with its progressive renewable energy policy, as an important market for us and where we will continue to explore additional projects. The synergies that derive from adding units to the existing complex allow smaller plants to be a cost effective and provide the additional power that the country needs in record speeds.”

CRS Announces Green-e Certification

A new Green-e certification program has been launched by the Center for Resource Solutions. The program is targeted to organizations that build clean energy projects or contract for renewable energy from these facilities. Apple, who received the 2014 Green Power Leadership Awards, is the first company to participate in Green-e Direct, which certifies the energy that the company generates from renewable resources and purchases directly including solar, wind and geothermal energy.

Green-e worked closely with Apple to develop the new certification option that offers independent, third-party oversight over the renewable electricity’s chain of custody beginning with generation and ending at retirement. Green-e Direct also offers participants assurance that the electricity will not be double-counted or double-claimed by regulations or other electricity users, and confirmation that the electricity meets the environmental quality requirements in the Green-e Energy National Standard.

Green-e Direct“We developed this new Green-e certification option so that renewable energy leaders like Apple can have the assurances and recognition of Green-e certification for their direct renewable energy purchases and onsite generation,” said Jennifer Martin, executive director of the nonprofit Center for Resource Solutions. “We are excited to continue working with Apple as they set the example for companies looking to power their operations with 100% renewable energy.”

Green-e Direct is intended to encourage long-term commitments by organizations that want to reduce the environmental impact of their electricity use, while providing a way to help recognize and promote leading companies that invest in clean energy. Renewable electricity certified through Green-e is subject to an extensive third-party verification process that ensures the energy meets the highest standards for quality in North America, and is eligible for use in a wide range of environmental standards, including LEED, B Corp., and Cradle to Cradle.

Martin added, “Green-e Direct reduces some of the complexity and uncertainty for companies that contract directly for clean energy. They want a clear message to their stakeholders about the difference they are making, and we can guide them through the complicated tracking and claims process, while certifying their clean energy use.”

Green-e Direct is available through Green-e, a nonprofit certification program that certifies renewable energy that meets environmental and consumer protection standards developed in conjunction with leading environmental, energy, and policy organizations.

U.S. Census Bureau Releases Renewable Energy Stats

For the first time the U.S. Census Bureau is now publishing economic census statistics for wind, geothermal, biomass and solar electric power generation. Between 2007 and 2012 revenues rose 49 percent from $6.6 billion to $9.8 billion. The electric power generation industry saw an overall decline of 1.2 percent in revenues from $121.0 billion to $119.5 billion between 2007 and 2012. The overall decline was driven by the fossil fuel electric power generation industry, which saw revenues decrease from $85.4 billion to $79.7 billion, or 6.7 percent, during the same five-year period.

Renewable Energy RevenueIn the 2007 Economic Census, wind, geothermal, biomass, and solar electric power generation were included in the broad “other electric power generation” industry but were not given separate designations. Beginning in the 2012 Economic Census, these industries had been broken out with the “other electric power generation” industry limited to only tidal electric power generation and other electric power generation facilities not elsewhere classified. Among the newly delineated industries (wind, geothermal, biomass, solar and other electric power generation), the number of establishments more than doubled in five years, from 312 in 2007 to 697 in 2012.

“As industries evolve, so does the Census Bureau to continue to collect relevant data that informs America’s business decisions,” said Census Bureau Director John H. Thompson. “Industries that use renewable energy resources are still relatively small, but they are rapidly growing.”

Specifically revenues for the wind electric power generation industry totaled $5.0 billion in 2012, the highest revenues among the industries using renewable energy resources. Hydroelectric power generation followed with revenues of $2.4 billion. Geothermal electric power generation had revenues of just under $1 billion ($995.4 million), followed by biomass electric power generation, with $934.6 million in revenues, solar electric power generation, with $472.4 million, and other electric power generation, with $59.0 million.

Together, these industries were a relatively small portion of the electric power generation industry, collectively accounting for just 8.2 percent ($9.8 billion) of total industry revenues in 2012. Fossil fuel and nuclear electric power generation are still the major revenue sources of the electric power generation industry, comprising 66.7 percent ($79.7 billion) and 25.1 percent ($29.9 billion), respectively, of total revenues.

Enel Green Power to Construct Geo/Biomass Plant

Geothermal energy in ItalyEnel Green Power has begun construction on its “Cornia 2″ geothermal power plant in Tuscany. When complete, this will be what the company believes is the first plant in the world that will use biomass to heat the geothermal steam as a means to increase energy efficiency as well as electricity output of the geothermal cycle.

The biomass will be sourced locally within a 70 km radius from the plant and produce 5 MW of power. Utilizing the biomass, the steam entering the plant will be heated to raise the initial temperature to between 370°-380° from 150°-160°. This will increase net capacity for power generation due to the greater enthalpy of the steam and the enhanced efficiency of the cycle caused by lower humidity in the generation phase. Currently the plant has 13 MW installed capacity. When the upgrades are complete in early 2015 the biomass/geothermal plant will increase capacity by 37 Gwh.

“Thanks to its century-long experience in geothermal energy, Tuscany is already in the future,” said the CEO of Enel Green Power, Francesco Venturini, “Hybrid technologies are the new frontier of renewable energy in our efforts to optimize performance, and this facility, which offers an innovative approach to integrating biomass and geothermal energy, is a replicable model that can open new prospects for the development of energy, the economy and employment for local communities.”

U.S. Renewable Energy Industry Ready to Step Up

A new goal was announced during the Asia-Pacific Economic Cooperation (APEC) summit in Beijing this week to double renewable energy in the 21 member economies by 2030. The renewable energy industry collectively came out and said they are ready to do their part. This new goal was a follow-up to last year’s commitment to encourage technology transfer and efforts to lower costs and attract private investment to the renewable energy industry.

“We appreciate the leadership that President Obama and the rest of these world leaders are showing on the critical task of rapidly scaling up low-carbon energy sources,” said Tom Kiernan, CEO of the American Wind Energy Association. “Here in America, according to the U.S. Department of Energy’s Wind Vision for the growth of our industry, we can quadruple wind power by 2030 and save consumers money doing it, if policymakers keep supporting state renewable standards and federal tax incentives to attract the necessary private investment.”

Linda Church Ciocci, executive director, National Hydropower Association said on behalf of the hydro electric industry, “Hydropower is poised for growth and ready to meet America’s renewable energy goals. From powering the 97 percent of the nation’s dams that remain unpowered to upgrading our existing facilities, opportunities exist to double hydropower’s contribution to the electricity grid, while strengthening our economy and providing more Americans access to clean, low-cost electricity.”

“GEA applauds the APEC goal of doubling renewable power,” added Karl Gawell, executive director, Geothermal Energy Association. “New geothermal power development underway in the U.S. and nearly all of the APEC countries will provide more than electricity, building thousands of megawatts of new geothermal power will spur economic growth, create new jobs and ensure environmental health for future generations.”

The highlight of the summit was a surprise negotiated emissions deal between the U.S. and China to curb climate change. The deal includes new targets for the U.S. and China to stop emission growth by 2030 and to create momentum around climate talks leading into the global climate conference taking place in Paris in 2015.

GDA Commissions Geothermal Plant in Indonesia

Ulumbu geothermal power plantThe Ulumbu 2 x 2.5 MW Geothermal Power Plant, located in Indonesia, has been commissioned and is now providing base load power for the local grid. The project was designed and developed by Geothermal Development Associates (GDA) who also provided major equipment including the steam turbine generator sets. In addition, GDS manufactured auxiliary equipment packages to minimize installation time, including the lube oil system, turbine inlet control valve assembly, and the plant control system.

PT Rekadaya Elektrika (Rekadaya) of Indonesia served as the general contractor, responsible for construction of the plant. Throughout 2014, GDA engineers were on-site working closely with Rekadaya engineers and construction crews to erect the plant and subsequent commissioning and performance testing. PLN UIP XI-UPK 3 formally handed the power plant over to PLN Wilayah NTT in a Taking Over Ceremony on September 4, 2014.

PLN is Indonesia’s state owned electricity company with a total installed electric capacity of 34,205 MW as of December 2013, of which 568 MW (2%) were geothermal. The Ulumbu geothermal field is located 13 km to the south of Ruteng, the capital of Central Manggarai Regency, Flores Island, in the East Nusa Tenggara Province of Indonesia.

ONR Expands Green Reach in Asia-Pacific

The Office of Naval Research (ONR) is expanding its work in Asia-Pacific’s renewable energy sector. The announcement was made during National Energy Action Month where the Navy is promoting energy efficiency and conservation by participating in and hosting events around the world. The announcement comes after ONR’s work with the Chiang Mai World Green City that was established two years ago at Chiang Mai Rajabhat University with support from ONR. It uses solar cells, batteries for energy storage and a direct-current (DC) microgrid to power more than 20 buildings over 200 acres, including residences, offices, businesses and a vegetable farm.

Navy National Energy Month poster“Each new partnership we establish moves the United States and our allies closer to energy independence,” said Dr. Richard Carlin, head of ONR’s Sea Warfare and Weapons Department. “This system is unique in that it uses direct current to power an entire community. While this concept is perfect for isolated and remote communities, it also could be used in the future on naval installations and even ships at sea to bring power to our Sailors and Marines wherever they are.”

Scientists in Thailand plan to establish another smart grid-powered village at the University of Phayao and introduce sustainable technologies to military barracks and other communities throughout the country.

ONR now has turned its attention to Vietnam, where there is an abundance of solar, biomass, wind, geothermal, hydro and other rich renewable energy sources. The U.S.-Vietnam collaboration also will take advantage of investments made in Hawaii, where ONR is sponsoring a study of electrical grids for three naval bases. As part of that initiative, the Hawaii Natural Energy Institute (HNEI) and the Applied Research Laboratory at the University of Hawaii are working with the Naval Facilities Engineering Command to develop an action plan for the Navy’s energy needs in Hawaii.

“We are expanding our research collaboration to Vietnam to build off the success in Thailand and to support the United States in our pivot to the Asia-Pacific region,” said Dr. Cung Vu, ONR Global associate director for power and energy. “Vietnam’s remote rural, mountainous and island areas will benefit from ONR’s microgrid research, and the Navy will be able to increase its understanding of energy-efficient technologies through another key partnership.”

Renewables Continue to Gain Ground

Renewables continue to gain ground according to the latest “Energy Infrastructure Update” report renewable energy sources including biomass, geothermal, hydropower, solar and wind, account for more than 40.61 percent of all new U.S. electrical generating capacity installed during the first nine months of 2014. Only natural gas provided more new generating capacity. The report was published by the Federal Energy Regulatory Commission’s Office of Energy Projects (FERC).

Wind EnergyNew capacity in 2014 from the combination of renewable energy sources is nearly 35 times that of coal, oil and nuclear combined (3,598 MW vs. 104 MW). When looking at just September, renewable energy sources accounted for 2/3 of the 603 MW of new generating capacity put in service (367 MW of wind/60.8% plus 41 MW of solar/6.8%).

Of the 8,860 MW of new generating capacity from all sources installed since January 1, 2014, 187 “units” of solar accounted for 1,671 MW (18.86%), followed by 28 units of wind 1,614 MW (18.22%), 7 units of hydropower 141 MW (1.59%), 38 units of biomass 140 MW (1.58%), and 5 units of geothermal 32 MW (0.36%). The balance came from 41 units of natural gas 5,153 MW (58.16%), 1 unit of nuclear 71 MW (0.80%), 11 units of oil 33 MW (0.37%), and 6 units of “other” 7 MW (0.08%). There has been no new coal capacity added thus far in 2014.

Comparing the first nine months of 2014 to the same period in 2013, new generating capacity from renewable energy sources grew by 11.8 percent (3,598 MW vs. 3,218 MW). Renewable energy sources now account for 16.35 percent of total installed operating generating capacity in the U.S. – up from 15.68 percent a year earlier: water – 8.45 percent, wind – 5.35 percent, biomass – 1.38 percent, solar – 0.84 percent, and geothermal steam – 0.33 percent. Renewable energy capacity is now greater than that of nuclear (9.23%) and oil (3.97%) combined.

“The steady and rapid growth of renewable energy is unlikely to abate as prices continue to drop and the technologies continue to improve,” commented Ken Bossong, executive director of the SUN DAY Campaign. “The era of coal, oil, and nuclear is drawing to a close; the age of renewable energy is now upon us.”

CEC Funds Geyser Study

The California Energy Commission (CEC) has awarded a $3 million grant to Calpine Corporation’s subsidiary Geyers Power Company for their “Advancing Utility-Scale Clean Energy” proposal. The grant will be matched by Calpine. The focus of the study is to determine how The Geysers may be modified to improve flexibility and address greater demands on the grid due to intermittent renewables.

“The Geysers is a true treasure of California,” said Joseph Ronan, senior advisor of government and regulatory affairs for The Geyers geothermal power plantCalpine. “In continual operation for over 50 years, this keystone resource will continue to play a major role in helping California meet its renewable energy and climate objectives for years to come.”

The Geysers is the world’s largest geothermal resource developed for electric generation and produces approximately 6 million megawatt hours of electricity equating to more than 15 percent of the delivered renewable energy in California.

Jim Kluesener, vp of geothermal operations for Calpine added, “While The Geysers currently offers a considerable amount of flexibility and shaping to the system, we have been analyzing new ways to operate our facility with even greater responsiveness to changing demand. This grant will enhance our ability to support the reliability needs of the system from this renewable and low-carbon resource. We are appreciative of the support from the CEC and other California energy stakeholders in considering the role of The Geysers in meeting the challenges associated with integrating other renewable technologies into the grid.”

How to Power Up Clean Power Plan

According to an analysis conduced by the Union of Concern Scientists (UCS), states can cost-effectively produce nearly twice as much renewable electricity as the Environmental Protection Agency (EPA) calculated in the Clean Power Plan. Increased renewable electricity growth could allow states to collectively cut heat-trapping carbon emissions from power plants by as much as 40 percent below 2005 levels rather than the 30 percent reduction the EPA included in its draft rule.

EPA-targets-are-modestOverall the EPA calculated that renewables could comprise 12 percent of U.S. electricity sales in 2030, marginally more than business-as-usual projections from the Energy Information Administration (EIA). If fully implemented, UCS’s proposed modified approach for setting state targets would result in renewables supplying at least 23 percent of national power sales by 2030.

“There is an urgent need to reduce heat trapping gases, and power plants are about forty percent of the problem,” said Ken Kimmell, UCS’s president and former head of the Massachusetts Department of Environmental Protection. “Fortunately, renewable electricity has been growing by leaps and bounds for the past five years and costs keep dropping. That’s great news and the agency should take full advantage of what’s been happening on the ground.”

UCS’s analysis found that seven states are already producing more renewable electricity than EPA computed they could in 2030 under its draft rule. Additionally, 17 states have existing laws that require more renewable electricity than EPA’s targets. Continue reading

10 Facts About Geothermal Energy in Oregon

geothermal power plantThe GRC Annul Meeting and Geothermal Energy Expo is taking place September 28-October 1, 2014 in Portland, Oregon. To get people excited, the Geothermal Energy Association has created 10 facts about geothermal energy in Oregon.

  1. There is about 33 MW of geothermal power on-line in Oregon producing 165 GWh in 2013.
  2. The latest industry survey identified 19 projects under development in Oregon with estimated subsurface resources of 340 MW that developers expect could provide 60 MW of additional power within the next few years if appropriate contracts are secured.
  3. The U.S. Geological Survey estimates that there are an additional 500 MW of discovered geothermal power resources in Oregon and 1,800 MW of undiscovered resources.
  4. Geothermal power provides affordable power according to studies produced in 2014 by the Energy Information Agency, Bloomberg New Energy Finance, California Public Utilities Commission and others.
  5. Geothermal power provides significant numbers of permanent jobs. For every 100MW of geothermal power there are 170 permanent jobs supported and development of 100MW of new projects produces over 600 annual construction and manufacturing jobs.
  6. According to studies geothermal has the lowest life-cycle emission of any renewable technology besides hydropower.
  7. Geothermal power projects have the lowest land density compared to any other renewable power technology.
  8. Geothermal power plants can be engineered to be firm and flexible power sources in addition to being source of a renewable baseload power.
  9. Geothermal fields can operate for 30 years or longer, the largest geothermal field in North America, the Geysers in California celebrated its 50th birthday this year. Geothermal fields in Italy have been generating electricity since 1912.
  10. Every additional megawatt of geothermal power can enable the installation of 3 to 5 megawatt of additional intermittent power like solar and wind power.

Polar Bears to Warm Up Elephants at Oregon Zoo

H_slinky-infographic-3What in the world do polar bears and elephants have to do with renewable energy? Lots with a creative use of geothermal energy at the Oregon Zoo where an underground heating-cooling system will improve energy efficiency. Polar bears like it cool and elephants like it hot and with the help of “Slinky” or a geothermal loop, the two endangered species will keep each other comfy. The innovative high-tech system will be buried 12 feet underground.

“Essentially, this system works the same way as your household refrigerator,” explained Jim Mitchell, zoo construction manager. “The condenser that cools the coils in your refrigerator produces heat, which is expelled away from the coils with a fan. Our system has just added another step: capturing that heat for use elsewhere rather than blowing it all away.”

According to Mitchell, heat is created as a byproduct of cooling the polar bear swimming pools at the zoo. And rather than just expel that heat, the geothermal system will direct it through rows of Slinky-like coiled pipes buried deep in the northern section of Elephant Lands.

The ground maintains a constant temperature, insulating the pipes. Then, when it’s time to crank the thermostat, pumps connected to the system will deliver heat to Forest Hall, the 32,000-square-foot indoor portion of Elephant Lands.

The geothermal loop and other energy-efficient design systems are expected to cut Elephant Lands’ energy requirements in half, reduce greenhouse gas emissions by 40 percent and serve as the primary heat source for what will be one of the country’s largest indoor elephant facilities.

Eventually, other renewable sources of heat will be fed into the geothermal system. While it won’t be readily apparent to visitors, the roof at Forest Hall will feature a huge array of solar panels.

“Gradually, we may eliminate the need for fossil fuels at the majority of buildings and exhibits at the zoo,” Mitchell said.

Curator Bob Lee, who oversees the zoo’s elephant program said of the project, “The beauty of this system is in how it gives elephants choice. Most of the time, the elephant family will be able to move freely indoors and out, and we’ll be able to sustainably maintain a comfortable temperature for them.”

Western US Slowly Adopts Geothermal Energy

EIA operational geothermal plants in USCalifornia has been the leading geothermal energy state in the U.S. but according to a recent Today in Energy published by the Energy Information Administration (EIA) other western states are slowing adopting geothermal energy.

There are currently 64 operating conventional geothermal power plants in the U.S., accounting for nearly 2,700 megawatts (MW) of total capacity at the end of 2013 or 0.4 percent of total U.S. generation. Over three-fourths of U.S. geothermal power generation in 2013 was in California, largely because of favorable geothermal resources, policy, and market conditions in the state, according to Today in Energy. The largest group of geothermal power plants in the world, a complex called the Geysers, located in Northern California, has more than 700 MW of capacity.

Since 2001, only 7 of 30 new plants exceeding 1 MW have been built in California, where most available low-cost geothermal resources have previously been developed. Sixteen of those 30 plants built after 2001 are in Nevada, with the remainder in Oregon, Idaho, Utah, and Hawaii. Most of the newer plants are relatively small, and while geothermal generation rose 11% between 2008 and 2013, the geothermal share of total U.S. electricity generation has remained consistently around 0.4% since 2001.

Geothermal plants are virtually emissions free, and unlike renewable sources such as wind and solar, they provide an available, dispatchable source of baseload power that is able to operate at a relatively high capacity factor. EIA projects that geothermal electricity generation could more than quadruple between 2012 and 2040 (increasing to over 67,000 GWh), helping California and other states with renewable portfolio standards satisfy their mandated renewable generation requirements.

Renewable Energy Continues to Gain

Renewable energy continues to gain as for the month of July all new U.S. electrical generating capacity put into service was from renewable sources according to the latest “Energy Infrastructure Update“. The Federal Energy Regulatory Commission’s Office of Energy Project’s report fond that there was 379 MW of wind installed, 21 MW of solar and 5 MW of hydropower.

Office of Energy Projects July 2014 Energy Infrastructure UpdateFor the first seven months of 2014, renewable energy has accounted for more than half (53.8%) of the 4,758 MW of new U.S. electrical capacity that has come on line with solar (25.8%) and wind (25.1%) each accounting for more than a quarter of the total. In addition, biomass provided 1.8 percent, geothermal 0.7 percent, and hydropower 0.4 percent. As for the balance, natural gas accounted for 45.9 percent while a small fraction (0.3 percent) came from oil and “other” combined. There has been no new electrical generating capacity from either coal or nuclear thus far in 2014.

Renewable energy sources now account for 16.3 percent of total installed operating generating capacity in the U.S.:

  • Water – 8.57%
  • Wind – 5.26%
  • Biomass – 1.37%
  • Solar – 0.75%
  • Geothermal steam – 0.33%

“This is not the first time in recent years that all new electrical generating capacity for a given month has come from renewable energy sources,” noted Ken Bossong, Executive Director of the SUN DAY Campaign. “And it is likely to become an ever more frequent occurrence in the months and years ahead.”

Geothermal: Technology Beneficial & Affordable

Last week nearly 300 geothermal energy leaders gathered in Reno, Nevada for the Geothermal Energy Association (GEA) National Geothermal Summit. The industry discusses many key issues including moving geothermal forward in Nevada; utility perspective on renewable portfolio standards and geothermal; the future of the renewable portfolio standard (RPS); tax incentive perspectives; achieving the potential of the Salton Sea and Salton Sea Restoration Initiative; protecting the existing industry base; and regulatory matters including leasing, permitting, and sage grouse habitat considerations.

“Geothermal is a viable, affordable technology with large amounts of untapped resource, and we can provide clean energy to the West as well as jobs and economic growth,” said GEA Executive Director Karl Gawell. “Despite uncertainties in geothermal policies we’re still seeing a growing and innovating industry, but the next five years will be critical.”

Geothermal Energy Summit - photo credit from DreamstimeDuring the Summit, the industry expressed concern over policy uncertainties, which continue to create barriers to growth, while calling for stable policies that will foster the developing technology. Besides extending tax credits, many leaders agreed that not much can be expected at a federal level. Instead, the focus was on states as the drivers for growth, with sustained growth expected in Nevada and California, and new projects in development in Utah, Oregon and Washington, among others.

Ormat Technologies was the Summit co-host. Bob Sullivan, vice president of business development, Ormat Technologies, said the U.S. is in “a period of significant change in the electrical grid.” Sullivan called the technology a “flexibility procurement” and said it is “one of geothermal’s hidden attributes.” Geothermal’s flexible dispatchability addresses a growing intermittence issue, he said. In the past, Sullivan said, geothermal has been “pigeon-holed” under Renewable Energy Certificates (RECs), “but it can be so much more than that,” he said. “It has all the attributes of a coal facility, the backbone of our electrical grid that we count on it day in and day out. Coal is being replaced with intermittents that you can’t count on, that need backup power. Geothermal provides inertia and voltage regulation, and also provides the green attributes.”

Sullivan continued, “On top of that it’s a real economic job engine. Our investment significantly positively impacts the local communities that we build in, so it has a big economic footprint, and it creates more jobs than any other renewable technology out there. As a baseload technology, geothermal can back up intermittent resources with no carbon footprint at all.”

Terry Page, director of regulatory affairs innovation with Enel Green Power, noted there is renewed interest in California for geothermal technology as the state recognizes some of the shortfalls of bringing on too much intermittent solar and wind power. “The Geothermal Energy Association is an international organization, and there’s a lot of activity particularly in Africa and other nations. But we’re beginning to see renewed interest in geothermal in California because of SB 1139, and Nevada because of SB 123. Both of those bills have generated a debate about what kind of renewables we need. For example, in California with the wind and solar resources, there’s a significant shortfall when the sun doesn’t shine and the wind doesn’t blow. The kind of projects Enel focuses on tend to mitigate that [through hybrid technologies],” Page noted.

In addition, Doug Hollett, program director for the U.S. Department of Energy Geothermal Technologies Office noted the agency seeks to advance the technologies and drive down the cost of developing attractive geothermal resources. “We’re seeing greater market awareness and increased exploration activities. Our feeling is that trend will continue. We’ve got a lot of geothermal out there that we sometimes forget to mention, Alaska, Hawaii. In some places it ends up offsetting diesel, which is just a wonderful story.”
