How Merthen Manor Heats Family Home And Six Cottages And Saves £20,000 Per Year In Fuel Bills
The biomass district heating system provides heat and hot water to the whole estate throughout the year, predictable fuel bills, income from the renewable heat incentive (RHI), and a 43,000kg reduction in CO2 emissions per year.
The Dark Side of Renewable Energy: Negative Impacts of Renewables on the Environment
What scientists, engineers, companies, and nations expanding their power capacities need to focus on, is implementing solutions that keep negative impacts of renewables in check.

Hillary Clinton is calling for a 700% increase in solar power. Is that realistic?
Brad Plumer for VOX: In the coming months, Hillary Clinton's campaign is planning to release a series of proposals for dealing with global warming. Her first installment is out Sunday evening, and it calls for a large increase in renewable power.
Specifically, she's proposing to boost the amount of wind, solar, and other renewables so that they provide 33 percent of America's electricity by 2027 — enough to power every home in the country.
Part of her plan would involve accelerating the recent rapid growth of solar installations nationwide. In her proposal, Clinton calls for US solar power to grow 700 percent from current levels.
That sounds like an impossibly large number, but it's not implausible on its face. US solar capacity grew 418 percent between 2010 and 2014 (because it was starting from a small base). So 700 percent growth by 2027 is at least within the realm of possibility. But it would require additional policy changes — and clean energy prices would have to keep dropping. Cont'd...

Is India Ready to Be a Solar Power Leader?
By RUPA SUBRAMANYA for ForeignPolicy.com: Is India ripe for a renewable energy revolution? Foreign investors certainly seem to think so, and renewables have been a signature issue for Prime Minister Narendra Modi. But if revolution is indeed underway, it isn’t a spontaneous one. And taxpayer money — not just from India — is fueling the surge.
New Delhi’s renewable energy aspirations recently received a major boost when Japan’s SoftBank announced a joint venture with Indian conglomerate Bharti Enterprises and Taiwan’s Foxconn Technology Group to create a new, Japanese-owned company that will bid on power contracts in India’s growing solar sector. Renewable energy, including solar, is a priority for Modi and has been since before he became the country’s leader last year. “The time has arrived for a saffron revolution, and the color of energy is saffron,” he saidon the campaign trail in 2014, attempting to symbolically link the sacred color of Hindus and his Bharatiya Janata Party with his energy dream. This joint venture is the first major announcement by a foreign investor that could help make that dream a reality. Cont'd...

Study: U.S. could run entirely on renewable energy by 2050
A new study has mapped out a potential plan for the United States to completely transition to clean, renewable energy by 2050.
According to the research study leader Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford, the process would demand significant upfront costs, but over time would be roughly equal to the costs of maintaining the fossil fuel infrastructure currently in place.
“When you account for the health and climate costs – as well as the rising price of fossil fuels – wind, water and solar are half the cost of conventional systems,” Jacobson said. “A conversion of this scale would also create jobs, stabilize fuel prices, reduce pollution-related health problems and eliminate emissions from the United States. There is very little downside to a conversion, at least based on this science.”
Among the positives of switching to clean energy: reducing air pollution in the U.S. that is responsible for approximately 63,000 Americans each year, and eliminating greenhouse gases produced by fossil fuel that would cost the world approximately $3.3 trillion per year by 2050, per a phys.org report.

Biomass Power Generation - A solution to Aggressive Green Power Strategies
A confluence of industry drivers such as regulatory framework and government support, long-term supply of low cost feedstock, and FITs and tax incentives for biomass energy use are anticipated to propel the use of biomass for energy generation.
Hawaii Lawmakers Pass Nation's First 100% Renewable Energy Requirement
Hawaii lawmakers voted 74-2 this week to pass the nation's first 100% renewable energy requirement. The measure, House Bill 623, makes Hawaii a global leader in renewable energy policy by requiring that 100% of the islands' electricity must be generated from renewable energy resources--such as wind, solar, and geothermal-no later than 2045.
"Hawaii lawmakers made history passing this legislation--not only for the islands, but for the planet," said Jeff Mikulina, Executive Director of the Blue Planet Foundation.
The measure, if enacted by Governor David Ige, would make Hawaii the first state in the nation with such a 100% renewable energy standard. Blue Planet Foundation, whose mission is to clear the path for 100% renewable energy, praised the move.
"Passage of this measure is a historic step towards a fossil fuel free Hawaii," said Mikulina. "This visionary policy is a promise to future generations that their lives will be powered not by climate-changing fossil fuel, but by clean, local, and sustainable sources of energy."
Interview with Neil Fromer, Executive Director, Caltech Resnick Sustainability Institute
We have researchers here developing systems that should be able to convert more than 40% of the incoming sunlight to electricity (current panels are ~20% efficient). We are also working with research groups that can generate fuels and chemicals directly form sunlight, or from biomass, hopefully at an efficiency and cost that will replace conventional fossil fuel materials.
Can We Save Energy with Vehicle Tires?
Tires may seem to be an unlikely eco-product. But, according to a new market report from Smithers Rapra, the global market for "green tires" will reach $70.6 billion by 2017 or 28% of the total tire market.
