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.

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.
In The Midst Of Toxic Oil Spill, Vancouver Announces It Will Go 100 Percent Renewable
There’s some mixed news coming out of Vancouver, Canada this week. On the one hand, the city announced at an international sustainability summit that it would commit to using 100 percent renewable energy to power its electricity, transportation, heating and air conditioning within 20 years. On the other hand, Vancouver is also dealing with a fuel spill in the waters of English Bay that is washing up on beaches and threatening wildlife.
On March 26, Vancouver’s city council voted unanimously to approve Mayor Gregor Robertson motion calling for a long-term commitment to deriving all of the city’s energy from renewable sources. At the ICLEI World Congress 2015 this week in Seoul, South Korea, the city went a step further, committing to reaching that goal of 100 percent renewable electricity, transportation, heating and air conditioning by 2030 or 2035.
Right now, Vancouver gets 32 percent of its energy — that includes electricity, transportation, heating, and cooling — from renewable sources, so the goal is ambitious, but not impossible. According to the Guardian, Vancouver could get all of its electricity from renewables within a few years, but transportation, heating, and cooling may prove more difficult.
As California Faces Record Drought Levels, Wind Energy Provides A Vital Service
In 2014, wind energy saved 2.5 billion gallons of water in California by displacing water consumption at the state's fossil-fired power plants, playing a valuable role in alleviating the state's record drought. Wind energy's annual water savings work out to around 65 gallons per person in the state - or the equivalent of 20 billion bottles of water, according to the American Wind Energy Association (AWEA).
According to AWEA, one of wind energy's most overlooked benefits is that it requires virtually no water to produce electricity while almost all other electricity sources evaporate tremendous amounts of water.
In California - where the state is combating record drought levels - Gov. Jerry Brown recently signed an executive order to reduce household water consumption by 25%, from about 140 gallons per day per household to 105 gallons. Wind energy's water savings are, therefore, equivalent to what would be saved by nearly one week's worth of the required reductions for a typical household.
In 2008, U.S. thermal power plants withdrew 22 trillion to 62 trillion gallons of freshwater from rivers, lakes, streams and aquifers and consumed 1 trillion to 2 trillion gallons. By displacing generation from these conventional power plants, U.S. wind energy currently saves around 35 billion gallons of water per year - the equivalent of 120 gallons per person or 285 billion bottles of water.
Retrofitting Buildings to Improve Energy Efficiency
Making a building more sustainable while completing the retrofit could attract more higher-paying tenants, which would cause a greater appreciation by the time the owners plan to sell. Properties with Energy Star certification have sold for 2-5% more than buildings without such certification.
