Developing a cheaper, more efficient means of fabricating solar photovoltaic (PV) cells could revitalize U.S. solar PV manufacturing, a technology invented here in the U.S. That’s in addition to helping realize the Department of Energy’s (DOE) SunShot Initiative goals of driving the cost of installed solar power capacity under $1 per watt — a level competitive with fossil fuel-fired electricity generation.
U.S. solar silicon manufacturing startup Crystal Solar — with the help of the U.S. DOE’s National Renewable Energy Laboratory (NREL) — has developed a new method for fabricating high-quality, high-efficiency monocrystalline solar silicon wafers at 100 times the throughput and half the cost of traditional methods.
Crystal Solar’s innovative approach to fabricating silicon solar wafers garnered it an “R&D 100” award as one of the top technology innovations of 2013. If Crystal Solar can scale-up production, the new method “could be a game-changer, creating American jobs and stemming the flow of solar cell manufacturing overseas,” CEO T.S. Ravi of the Santa Clara, California-based company stated in an NREL news release.
Momentum is finally building up in the U.S. offshore wind energy industry, the result of concerted clean energy policy and action plans enacted by the Obama administration. With 14 projects in advanced stages of development, the latest Department of Energy offshore wind report highlights progress across multiple fronts.
Taken together, pioneering projects hold out the potential to deliver some 4,900 megawatts of clean, renewable electricity to U.S. businesses and communities, according to the Offshore Wind Market and Economic Analysis: 2014 Annual Market Assessment report, produced by Navigant Research.
Building offshore wind energy farms also means a lot more in the way of green jobs and economic stimulus. It also drives innovation that will help keep U.S. industry competitive in cutting-edge wind and clean energy technologies. Furthermore, realizing U.S. offshore wind energy potential will be a big step forward in terms of reducing U.S. greenhouse gas emissions and dependence on fossil fuels. And that will be a big plus in terms of improving human and environmental health and safety, as well as reducing the potential for overseas conflicts.
Distributed solar photovoltaic (PV) energy systems, along with smart grid and energy storage capacity, will play a much larger role in Hawaii’s energy future if a recently proposed plan comes to fruition.
Pursuing a goal to achieve the highest level of renewable energy use in the U.S., Hawaiian Electric Co. proposes to nearly triple the amount of distributed solar power capacity coursing through its grid by 2030, as well as install smart grid and energy storage systems.
Almost completely reliant on fossil fuel imports for energy generation, electricity costs – as well associated costs in terms of human and environmental health and safety impacts – in Hawaii are roughly twice that of any other U.S. state. That’s changing for the better, however, as Hawaiians embrace renewable energy technology, enhance energy efficiency and try to dial down energy usage.
Hawaiian Electric’s plan sets a goal of sourcing 65 percent of electricity supply from renewable sources by 2030. Realizing this goal would drastically reduce Hawaii’s dependence on fossil fuel imports, greenhouse gas emissions and other pollution associated with fossil fuel use. In addition, Hawaiian Electric expects customers’ electric bills would be reduced by 20 percent.
More than 12,500 clean energy and transportation jobs were announced in this year’s second quarter (Q2 2014), more than double that of Q1, according to a report from Environmental Entrepreneurs (E2) on the eve of the Labor Day weekend.
The announcement of the Obama administration’s Clean Power Plan instilled confidence and greater certainty regarding the future of clean energy in the U.S. That, in turn, helped spur the jump in clean energy job announcements in Q2, Environmental Entrepreneurs stated in a press release.
“This Labor Day weekend, the story is that more Americans are working because of clean energy,” E2 Executive Director Bob Keefe was quoted as saying. “But to keep that growth going, we need our state and federal leaders to do their jobs too. We need them to support smart policies that grow our economy and protect our environment – policies like the federal Clean Power Plan.”
Imitating nature’s way of letting nothing to go to waste, materials researchers-turned-entrepreneurs are using the humble coconut husk to manufacture an expanding variety of useful, environmentally friendly products.
While husks are often discarded, they can be put to a variety of uses, such as binder-less particle board, sustainable packing material, automotive trunk liners and electric car battery pack covers. Additional applications include farm erosion netting, activated charcoal filters, potting materials and wall planters.
Also known as coir, the history of using coconut husks to manufacture a variety of natural bio-products goes back thousands of years. Today, it’s progressing hand-in-hand with an inclusive model of international development centered on sustainable local market and business development, job creation and the opening up of new opportunities that could raise the living standards of millions of families living in the tropics.
Young research-driven companies in Texas, such as Essentium Materials in College Station, embody social-enterprise and triple-bottom-line values in which ethics and justice underpin environmentally, socially and economically sustainable product and business development.
Integrated resource management based on principles of sustainability is touted as a means of addressing numerous and varied challenges. Ecosystems and natural resource degradation, greenhouse gas emissions, and issues of social and economic justice are prominent among them. UTZ Certified has been putting these claims to the test with its Energy from Coffee Wastewater project.
Launched in 2010 in partnership with coffee farmers and communities in Central America, the Energy from Coffee Wastewater project proves that it’s possible to generate renewable energy, tackle climate change, protect water resources, and raise locals’ health and living standards at the same time.
Custom-built coffee wastewater and solid waste treatment systems have been installed at eight coffee farms in Nicaragua, 10 in Honduras and one in Guatemala as part of the project. The positive impact on over 5,000 people living in these communities has been substantial enough for UTZ Certified to reproduce the initiative in other countries.
Persistence and grassroots political activism finally won out in Indianapolis recently: On August 15, Indianapolis Power & Light (IPL) announced it will stop burning coal at its 1,094-megawatt Harding Street power plant – the only coal-fired power plant remaining within the limits of a major Midwestern city – and switch to natural gas-fired electricity generation by 2016.
The announcement marked a big victory for “small ‘d’ democracy,” one Indianapolis City-County Council member remarked. It was also a win for Power Indy Forward, the broad-based coalition of environmental and public interest groups that came together to persuade IPL and government officials to phase out the use of coal in electricity generation. The coalition is also lobbying for environmental and social remediation efforts, energy efficiency programs and goals, and much more in the way of clean energy generation capacity.
“More than 55 organizations comprising the Power Indy Forward Coalition have been working hard for this day, and we thank IPL for making the decision to stop burning coal at the Harding Street plant. The community fought for clean air and a plan to protect the health of our families by phasing out coal in Marion County,” Jodi Perras, senior campaign representative for Sierra Club Indiana Beyond Coal, wrote in an August 15 op-ed in the Indianapolis Star.
Supportive market-driven policy mechanisms and government R&D funding have been seminal in the creation of what’s turned into a booming U.S. solar energy sector. Whether it’s at the utility-, commercial- or residential-scale, using photovoltaics (PV) to produce renewable energy from sunlight is now financially viable wherever you live the U.S., according to a new study from the Union of Concerned Scientists (UCS).
Past and present performance is no guarantee of future success, however. The looming 2016 expiration of a key federal tax incentive – the solar investment tax credit – along with sharp cutbacks in leading European solar energy markets, international trade disputes and the imposition of punitive tariffs, have prompted U.S. solar industry participants to reassess their business plans. And while rapid growth and industry downsizing have brought PV cell and module supply and demand into balance – leading some PV manufacturers to even add capacity – profit margins, and the margin for error, are generally razor-thin.
In Solar Power on the Rise: The Technologies and Policies behind a Booming Energy Sector, UCS’ Climate and Energy Program senior analysts John Rogers and Laura Wisland highlight the social, environmental and economic benefits of solar power: “The major drivers of the rapid adoption of solar power,” whether it be solar PV or concentrating solar power (CSP) technology. They then move on on to summarize “key steps to sustain the strong growth of solar power in the United States and its contribution to a more resilient electricity system in the decades ahead.”
Intelligent energy storage is emerging as a commercially-viable alternative to adding electricity generation capacity or constructing new power plants.
Equipped with energy management software that’s responsive to electricity demand and supply conditions, smart energy storage systems are also cropping up among commercial and industrial companies, municipalities and college campuses, helping boost energy efficiency, renewable energy-grid interconnections and reduce utility bills, as well as strains on the power grid.
Heightened interest and investment in intelligent energy storage is prompting industry participants to band together in more organized fashion. Bringing together energy storage policy, technology and market leaders, Energy Storage North America (ESNA) on August 18 announced finalists for its annual 2014 Innovation Award.
“This year’s ESNA Award finalists represent a rich diversity of players and business models in rapidly developing energy storage ecosystems across the U.S. and Canada,” Janice Lin, managing partner of Strategen Consulting and co-founder of the California Energy Storage Alliance, was quoted in a news release. “Energy storage as an asset class is a welcome addition to electric system planning toolkits in California, Hawaii, New York, Ontario and other markets.
Wetland restoration is an excellent means of water resource management and stewardship, due to its cost-effectiveness and sustainability. An April report from the Center for American Progress and Oxfam America revealed the remarkable economic value and benefits resulting from coastal ecosystem restoration projects around the U.S.
“We learned in a nutshell that there’s a win-win, if not a win-win-win, opportunity that presents itself when you invest in conservation. The economic benefits are remarkable … There’s a direct connection between what we’re doing to enhance the environment and what we’re doing to enhance economic opportunity,” summarized Mark Schaefer, National Oceanographic and Atmospheric Administration assistant secretary of commerce for conservation and management.
The U.S. Environmental Protection Agency (EPA) and partner organizations have been promoting use of “green infrastructure” for years “as part of a comprehensive approach to achieving healthier waters.” Recognizing excellence in such initiatives for the first time, EPA on August 19 awarded Volkswagen Group of America (VW) with the EPA Region 4 Rain-Catcher Award, Commercial Category during an awards ceremony at the EPA Region 4 International Erosion Control Association Municipal Wet Weather Stormwater Conference in Charlotte, North Carolina.
For reasons economic, social and environmental, a drive to boost efficiency and drastically cut down on waste of all types – materials, water and energy – is afoot across the U.S. Accurate, comprehensive and timely measurement and assessment of waste streams are prerequisites in order for any such plans to be realized successfully. Organizations such as UL Environment are stepping into the breach, establishing the tools, methods and standards necessary to measure, assess and drastically reduce waste streams across an expanding range of products and processes, as well as throughout organizations.
When it comes to reducing and managing solid waste streams, the UL ECVP 2799 “Zero-Waste-to-Landfill” validation refines the somewhat nebulous and variously defined concept of “zero waste.” With UL 2799, UL Environment sets out a comprehensive, rigorously-defined and independently-verified set of metrics and processes that a variety of leading companies are using to dramatically cut down the volume of solid waste being sent to landfills. In some cases, landfill waste has effectively been reduced to zero.
Aiming to advance development of efficient-vehicle technologies, the U.S. Department of Energy last week announced it will provide $55 million in funding for 31 projects “to accelerate research and development (R&D) of critical vehicle technologies that will improve fuel efficiency and reduce costs.”
Much of the funding is being devoted to projects that, in one way or another, will help realize the goals set out in President Barack Obama’s EV Everywhere Grand Challenge. Announced in March 2012, the challenge aims to reduce the costs and improve the performance of plug-in electric vehicles (PEVs) to the point where they “are as affordable and convenient as today’s gasoline-powered vehicles by 2022.”
DOE has invested $225 million in EV Everywhere projects to date in order to lower PEV costs, increase range and develop a PEV charging infrastructure. Among other achievements, EV Everywhere R&D projects have cut the cost of PEV batteries nearly in half, to $325/kilowatt-hour (kWh), since 2010.
The U.S. continues to be a world leader when it comes to installed wind power capacity, ranking second worldwide, despite modest growth in 2013. U.S. installed wind power capacity met nearly 4.5 percent of total national electricity demand last year, and U.S. renewable energy electricity generation is poised to double again by 2020, according to two reports released August 18 by the U.S. Department of Energy (DOE).
Persistence of key policy incentives is pivotal to ongoing growth in wind and renewable energy capacity, however, the DOE noted. With lobbying from Koch Industries’ Americans for Prosperity (AFP), Republican Gov. Sam Brownback of Kansas recently came out in favor of phasing out the federal wind energy production tax credit (PTC), which expired Dec. 31. Pushing for renewal of the wind energy PTC, the American Wind Energy Association (AWEA) recently ran TV and YouTube ads thanking members of Congress in Colorado and Iowa, for their strong, bi-partisan support of wind energy and the PTC renewal.
“As a readily expandable, domestic source of clean, renewable energy, wind power is paving the way to a low-carbon future that protects our air and water while providing affordable, renewable electricity to American families and businesses,” DOE Secretary Ernest Moniz was quoted in a news release. “However, the continued success of the U.S. wind industry highlights the importance of policies like the Production Tax Credit that provide a solid framework for America to lead the world in clean energy innovation while also keeping wind manufacturing and jobs in the U.S.”
Germany’s offshore wind investment received a big, much-needed boost on August 11 as Munich City Utilities and Sweden’s Vattenfall announced a huge wind-farm investment off the German North Sea coast.
Due to start construction in 2015 and come online in 2017, the $1.6 billion Sandbank offshore wind farm project entails Vattenfall installing 72 turbines off the German North Sea coast. That would add a massive 1.4 terawatt-hours (TWh) of clean, renewable electricity to the German grid, enough to supply some 400,000 homes, according to an AFP news report.
Nearly 39 gigawatts of new solar photovoltaic (PV) power generation capacity was installed worldwide in 2013, a 38 percent year-over-year increase. That brought the amount of solar power generation capacity installed worldwide as of end of last year to 140.6 GW, up from 101.9 GW in 2012, according to Hanergy Energy Holding Group and China New Energy Chamber of Commerce’s Global Renewable Energy Report 2014.
Hanergy and CNECC’s 2014 report shows a dramatic shift in the geography of solar power deployment last year, illustrating that installations in China, and the Asia-Pacific region more broadly, far outpaced those of Germany and Europe, as well as those for the U.S. and the Americas region.
While Germany and Europe have been scaling back government incentives to install solar and renewable energy systems, Japan instituted a generous solar energy feed-in tariff (FiT) in July 2012 in the wake of the Fukushima nuclear power plant disaster. Japan’s renewable power generation capacity rose by 5.86 million kilowatts with solar power accounting for 90 percent of the total, according to a Japan Times news report. That’s equal to the cumulative total in Japan prior to the launch of the solar FiT.
For its part, China has upped national strategic targets for new solar power generation capacity and has been reinforcing that with market-based incentives, focusing particularly on trying to stimulate uptake in the residential sector. Responding to growing public discontent, as well as the rapidly rising social, environmental and economic costs of its dependence on fossil fuels, China’s government is experimenting with solar and renewable energy FiTs and cap-and-trade markets. It’s also providing consumers incentives to purchase plug-in electric and fuel-cell electric vehicles (PEVs and FCEVs).
