Conservatives Lose Again, Trying to Eliminate Renewable Energy
SustainableBusiness.com News
In yet another attempt to eliminate renewable energy- this time in Colorado - conservatives lost in federal appeals court.
Judges unanimously upheld a lower court's ruling that Colorado's Renewable Portfolio Standard (RPS) is indeed constitutional. Ultra-right wing Energy and Environment Legal Institute (EELI - formerly the American Tradition Institute) brought the case, arguing that the RPS harms inter-state commerce.
EELI, which has ties to the coal industry, says that by requiring utilities to source a percentage of energy from renewables, it unlawfully regulates fossil fuels from out-of-state. They claim the mandate unfairly burdens coal company Alpha Natural Resources and others.
Judges say the plaintiffs "utterly failed" to show excessive burdens compared to local benefits.
"This is a landmark day. This ruling affirms the ability of states to choose their own energy future as part of a national framework and interstate commerce," says Tom Kiernan, CEO of American Wind Energy Association (AWEA). "The nation's 29 renewable energy standards continue to play a important role in diversifying the country's electricity portfolio's in order to advance key public policy interests - including protecting consumers against fuel-price risk, improving overall system reliability and creating significant clean air and water benefits such as reducing carbon pollution and conserving fresh water."
Colorado was the first state to adopt a RPS, voted in by citizens in a referendum. Wind power alone supports about 7,000 well-paying jobs, including manufacturing jobs at 22 factories in the state. The industry has attracted $7.8 billion in capital to Colorado's economy, says AWEA.
Colorado's RPS requires investor-owned utilities to use 30% renewable energy by 2020 and electric coops and municipal utilities to use 10-20% by 2020.

Fwd: First Solar Desalination Plant Will Serve California Farmers

First Solar Desalination Plant Will Serve California Farmers
SustainableBusiness.com News
After piloting its solar desalination process for two years, California-based WaterFX is about to build its first commercial plant to farmers in the Central Valley.
Its subsidiary, HydroRevolution, will use concentrating solar to turn salt water at farms into a sustainable fresh water supply. Rather than taking the water from the ocean, it will recycle unusable irrigation drainage water for use by local water districts.
Amazingly, it could turn farmers into water producers rather than consumers! And it could make all the difference for California farmers, where an estimated 1 million acre-feet of irrigation drainage water could be reused, according to Think Progress.
"The result could mirror what has happened in energy; rather than relying on large?scale, centralized generation, smaller "distributed" projects across the state could free up hundreds of thousands of acre?feet of water through reuse, reducing overall demand on the water grid," says the company.
HydroRevolution will expand the pilot plant, which has been operating since 2013, on 35 acres farmed with salt-tolerant crops.
How It Works
Its Aqua4TM technology produces heat from huge, parabolic solar reflectors. That heats mineral oil, which flows through a distillation system, evaporating fresh water and condensing brackish water into usable liquid, separating out the minerals.
"Water that dribbles down from nearby hills, and through the soil after being used for irrigation, collects so much salt, selenium, boron and other minerals that it's not fit for human consumption. The solar plant captures the runoff using a French drain-style system 6-8 feet under the crops, and sends the tainted water through pipes and tanks that heat it," explains the San Francisco Chronicle.
The water can be used again for irrigation, and the minerals are so efficiently distilled, they can be processed and sold - selenium and boron for vitamin supplements and gypsum for drywall, for example.
Aqua4 can treat any kind of wastewater, drainage water, runoff, saline groundwater and industrial process water ... all right on site through movable, module units. The resulting fresh water costs $450 per acre-foot - not much more than farmers typically pay - and about 75% less than conventional desalinated water.
In a unique move, HydroRevolution says it will use crowdsourcing to finance the plant's construction, allowing all California residents to participate as owners.
Another novel, environmentally superior desalination technology is being developed by Voltea, using electric fields to remove salts and dissolved solids from water. The modular devices have been miniaturized to the size of a coffee cup!, the company says. Another technologies uses wind, Wind4Water.

White House Mobilizes $4 Billion in Long-Term Renewable Energy Investments
SustainableBusiness.com News
Yesterday, the White House hosted a Clean Energy Investment Summit to mobilize more long term private investments in the industry.
Hundreds of organizations as diverse as the University of California, Goldman Sachs, and Sierra Club Foundation are among the long-term investors that committed $4 billion to back potentially breakthrough solutions for climate change through renewable energy technologies - double President Obama's goal.
The idea is to bring mission-driven investors together to amplify their impact and help those unfamiliar with the clean energy space.
This "will help ensure that even more American-made clean energy technologies can make the leap from an idea, to the laboratory, to the global marketplace," says Ernest Moniz, Secretary of Energy. "We've seen major advances in solar PV, wind power, advanced batteries, energy efficient lighting, and fuel cells, and we must continue investing," creating entirely new industries in America that reduce carbon pollution while growing the economy.
Piecing the Money Together to Mass Scale Clean Energy
"There's a whole set of funding sources we're going to need if we're going to deploy clean energy at scale. It's less about the specific amount of money that was committed today, and more about the structures that are being put together. You're looking at trillions of dollars in capital, but getting folks who run those funds up the learning curve, getting them comfortable with those types of investments, is the challenge," Dan Reicher, Director of Stanford University's Steyer-Taylor Center for Energy Policy and Finance, told The Guardian.
Indeed, the only way to keep temperature rise below 2C is to triple spending on clean energy research and development, says the International Energy Agency.
That's why these new initiatives are so important, the result of executive orders from President Obama:
- A Clean Energy Impact Investment Center at the Department of Energy will make information about the federal government's energy and climate programs more accessible and understandable to the public, including mission-driven investors. They will share research and contacts from DOE's research labs and developments in technologies, for example, in a modified matching service between investors and technology developers.
- The Treasury Department will issue guidance on impact investing to facilitate involvement from foundations. It will clarify, for example, that foundations can make certain "mission-related" investments in companies.
- The US Small Business Administration will offer improved financing options for private investment funds that raise long-term capital, including early-stage investors in capital-intensive clean energy technologies.
"Long-term investors -such as foundations, family office investors, and institutional investors - can play a catalytic role in accelerating the transition to a low-carbon economy. Philanthropists can help fund clean energy innovation at the earliest stages, where bold new ideas are emerging from our labs, universities, and startups, while investors can scale up the most promising of these innovations. Taken together, these efforts will help ensure that more climate innovations make the leap from the lab into the global marketplace," says the White House.
Another outcome of the summit is a decision form a nonprofit investment intermediary that identifies, screens, and assesses high-potential companies and projects worthy of investment. The consortium is allocating $1.2 billion to start, with a goal of mobilizing $2.5 billion over five years.
Their focus is on opportunities that don't fit into existing fund structures, moving companies and projects across the "valleys of death" - the difficult passage from lab to the marketplace. Investors include the University of California and TIAA-CREF.
Last year, Obama reached out to the private sector to scale commitments to use more renewable energy, improve energy efficiency and strengthen building codes.

Fwd: Diamond-Like Material Helps Solar Power Cast a Bigger Shadow

Diamond-Like Material Helps Solar Power Cast a Bigger Shadow
The energy usage curves of most industrial countries – or load curves - have long resembled a crumpled fedora hat.
They rise sharply at daybreak as people start brewing coffee and companies switch on machines, then peak twice – in the morning and the late afternoon, before dropping off after dinner. Utilities usually crank up their turbines and bring extra power plants online to cover the "peak" demand.
But on a sunny May 8, 2011, something unusual happened in Germany: this midday call for extra output didn't materialize. For the first time, the country had so many solar panels in use that utilities were able to supply all the energy needed to cover the bulge.
Although May 8 was a Sunday, a similar thing also happened the next day on Monday. "This is the first time solar power plants were able to deliver peak load," says Robert Roesner, high power electronics engineer at GE Global Research in Munich, Germany.
Above and below: Solar panel's covering the roof of a GE plant in Berlin, Germany. They supply electricity to the company first hybrid power plant.Solar panels are becoming so widespread that a new forecast from Bloomberg New Energy Finance estimates that by 2040, rooftop solar power will be cheaper than electricity in the grid in every major economy and will account for more than a third of new power capacity worldwide.
Roesner and his team in GE labs are now hoping to give this solar revolution a boost. They are using chips made from a material called silicon carbide (SiC) to build superefficient "inverters" that switch direct current (DC) generated by solar panels into alternating current (AC) that flows from the wall outlet.
"This material stands to revolutionize power electronics," says Danielle Merfeld, global technology director for electrical technologies and systems at GE Global Research.
SiC takes the best features from diamond, one of the toughest materials in the world, and combines them with the properties of silicon, which is inside every computer and every smart phone.
The results can be quite powerful. For example, SiC can shrink the size of a one megawatt inverter, which can supply 500 homes, by 35 percent. The material also allows engineers to switch DC to AC in tiny incremental steps, rather than big jumps, and increase power conversion efficiency by about 1 percent, compared to today's standards. "Right now inverters are about 98 percent efficient so a one percent gain may not seem like much," Roesner says. "But with the huge installed base, the gains will quickly add up."
So few losses also means that the converter doesn't generate as much heat and doesn't require a complex water-cooling system. "We switched from water cooling to air," says Tobias Schuetz, lead engineer for high power electronics at the Munich lab. "The design is cheaper and also more reliable."
The SiC inverter at the hybrid power plant in Berlin. Image credit: GE ReportsThe first prototype of the SiC inverter is already switching solar electricity from DC to AC in Berlin, Germany, where GE recently opened an innovativehybrid power plant suppling with electricity its local factory. Depending on price and availability, special software allows the manager to select the cheapest energy source between solar power, a gas engine, the grid, heat storage and even batteries.
Schuetz says solar power inverters are just the beginning. SiC chips can be applied inside any device that needs to switch power between AC and DC. They could make trains, planes and wind turbines much more efficient. "We call this idea where one technology serves multiple industries the GE store," Merfeld says.
These applications hadn't existed previously because the process to make SiC chips is quite onerous. For starters, SiC is extremely hard and the material's early applications included sandpaper and abrasives. It doesn't help that making a SiC chip involves up to 300 discrete steps in a clean room (see below).
But GE scientists have been studying the material for 50 years, starting with Robert Hall, the inventor of the first semiconductor laser. They came up with several breakthroughs, including the first practical and reliable power switch.
Building on these foundations, the company transfered technology and intellectual property valued at more than $100 million to a power electronics manufacturing consortium created in Albany, NY, in 2014.
The consortium, which includes GE, New York State, the SUNY Polytechnic Institute's Colleges of Nanoscale Science and Engineering, and other industry partners, is building a shared fabrication plant that will develop and produce silicon carbide power devices on six-inch wafers – a big deal when it comes to production efficiency.
"This will dramatically open up silicon carbide applications," Merfeld says. "We want people to come to New York and take advantage of the technology."

Five Seismic Shifts In Energy On the Way
SustainableBusiness.com News
Calling it "5 Seismic Shifts" in global power generation, Bloomberg New Energy Finance (BNEF) outlines the dominant trends we'll see over the next 25 years.
The big news is the scale of renewable energy investment we are about to see, especially in distributed solar energy. The bad news is that without more radical policies, continued fossil fuel emissions will prevent the world from reaching climate goals.
Solar, Solar Everywhere! Costs keep coming down in solar PV, driving a $3.7 trillion surge in solar investment, both large-scale and small-scale.
Power to the People: $2.2 trillion of that will go to rooftop and community-based solar systems, giving individuals and businesses electricity independence by storing it in batteries and giving billions in the developing world access to power for the first time.
Small solar and building-integrated solar will soar from 104 gigawatts in 2014 to nearly 1.8 terawatts in 2040, a 17-fold increase. Prices will drop another 47% per megawatt, conversion efficiencies will improve and the industry will move to new materials and more streamlined production methods.
"Up to now, small-scale solar investment has been dominated by wealthy countries such as Germany, the US and Japan. By 2040, developing economies will have spent $1 trillion on small PV systems, in many cases bringing electricity for the first time to remote villages," says Jenny Chase, chief solar analyst at BNEF.
Utility-scale solar PV will grow 24-fold to 1.9 terawatts, onshore wind will reach 1.8 terawatts (up five-fold) and offshore wind will grow 25 times to 198 gigawatts. Smart grid capacity will grow 17-fold to 858 GW.
By 2030, solar will be the cheapest energy resource and by 2040, the cost of wind projects will have dropped another 32%.
In fact, 78% of the $12.2 trillion invested in power generation will be in emerging markets. Renewables will account for two thirds of that, with $1.6 trillion still in coal, $1.2 trillion in gas and $1.3 trillion in nuclear.
For every 1 GW of new build in the Americas, 3.4 GW will be installed in Asia Pacific nations. China alone will attract $3.3 trillion, nearly double that for the Americas, BNEF says.
Solar Becomes Top Energy Source in 2018
Looking at the shorter term, GTM Research finds 2018 will be the tipping point for solar, when it achieves grid parity worldwide and becomes the energy of choice. By 2020, the world will be installing 135 gigawatts a year, triple the current pace.
The top countries will be China, US and Japan, and Africa, Latin America and the Mid-East will jump from 1% solar today to 17%.
Demand Undershoots: at the same time, ever-increasing energy efficient technologies of all kinds will limit energy demand growth to 1.8% a year, down from 3% a year from 1990-2012. In OECD countries, electricity demand will be lower in 2040 than in 2014.
Gas Flares Briefly: Natural gas will not be the world's "transition fuel" away from coal, except in the US. Many developing nations will opt for a twin-track of coal and renewables.
Climate Peril: Despite $8 trillion in renewable energy investments, there will still be enough fossil-fuel plants to keep world carbon emissions rising until 2029, and in 2040, emissions will still be 13% above 2014 levels. Fossil fuels will still be used for 44% of electricity production, down from 67% in 2014).
Even with much slower energy demand growth, the world will use 56% more electricity - too much of it from coal - as population and economies expand in developing countries.
"The CO2 content of the atmosphere is on course to exceed 450 parts per million by 2035 even if emissions stay constant, so the trend we show of rising emissions to 2029 makes it very unlikely that the world will be able to limit temperature increases to less than 2 degrees Centigrade," says Seb Henbest, head of Europe, Middle East and Africa for BNEF.
"The message for international negotiators preparing for the Paris climate change conference in December is that current policy settings - even combined with the vast strides renewables are making on competitiveness - will not be enough. Further policy action on emissions will be needed," he adds.
The analysis, however, leaves out key policies that have yet to be put in place, such as EPA's Clean Power Plan in the US or China's cap-and-trade systems, which starts official operations next year. In proceeding years, a worldwide cap-and-trade system will likely coalesce.

Milestone Passed: World Adds Over 100 GW of Renewables in 2014
SustainableBusiness.com News
2014 was another big year for renewable energy worldwide - for the first time, over 100 gigawatts (GW) were installed in one year.
The 103 GW added - mostly solar and wind - equals the output of all US nuclear plants combined, and is a significant increase from previous years - 86 GW in 2013, 89 GW in 2012 and 81 GW in 2011.
Renewables are edging toward supplying 10% of the world's power. They contributed 9.1% of all electricity in 2014, up from 8.5% the previous year, and that doesn't include big hydro.
The industry grew 17% with $270 billion invested, according to the 9th Annual Global Trends in Renewable Energy Investment 2015, by the United Nations Environment Program (UNEP) and Bloomberg New Energy Finance.
Even sharply lower oil prices didn't stop the growth, thanks to major expansions of solar in China and Japan and record investments in offshore wind.
"Once again in 2014, renewables made up nearly half of the net power capacity added worldwide" says Achim Steiner, UN Under-Secretary-General and Executive Director of UNEP.
"There is now nobody who thinks the energy system of the future will look like the energy system of the past," says Michael Liebreich, advisory board chair for Bloomberg New Energy Finance.
Solar and wind continue to dominate with 92% of all investments. Solar jumped 25% to $150 billion - its second highest figure ever - and wind rose 11% to a record $99.5 billion. 49 GW of wind and 46 GW of solar PV were added, both records.
Seven $1 billion-plus offshore wind projects were approved in Europe, including the biggest one ever - the $3.8 billion 600 megawatt Gemini project in the Netherlands. Geothermal grew 23% to $2.7 billion invested, but biofuels, biomass and small hydro declined.
China saw record investments of $83.3 billion (up 39% from 2013) and the US came in second at $38.3 billion, up 7% on the year. Japan is third at $35.7 billion, a 10% increase and its biggest year yet.

Brazil's energy regulator sets cap price for solar energy auction
29.07.2015: Brazil’s energy regulator ANEEL has set a cap price of 349 BRL ($103.8) per MWh for the Reserve Energy auction for solar power producers that will be held on Aug. 28, 2015. Through the auction, ANEEL will select exclusively solar projects. Projects selected in the auction, which must begin delivering power in August 2017, will sell their electricity output to the Brazilian grid under a 20-year PPA. In the Reserve Energy auction held in late 2014, ANEEL had set a starting maximum price of 262.0 BRL per MWh for solar projects. The auction, which also selected wind power projects with a combined capacity of 769 MW, ended with an average price of 169.82 BRL per MWh. Through this auction, ANEEL selected 31 PV projects with a combined capacity of 889.7 MW. © PHOTON
