Every year, American building owners lose billions of dollars as they overpay for energy to power their lighting, heating, and cooling systems, as energy is wasted in obsolete equipment or leaks out of a porous building envelope. The right energy efficiency measures can reduce costs by 20% to 40%, but they can also require substantial upfront sums. Additionally, (more…)
Despite strong sun and plenty of public support for the idea of energy self-reliance, the American southeast has not traditionally been a hot spot of solar adoption. That looks to be changing. With solar’s low cost now making it a real competitor with traditional fossil power, local citizens are increasingly calling on state leaders to put more of their homegrown sunshine to (more…)
Leaders from some of the largest pension funds in the U.S. and the world are concerned about the future profitability of fossil fuel companies, and they have asked those companies to report on their plans for managing a long-term shift toward renewable energy.
Managers of 70 major pension funds, which together (more…)
If you’ve not been paying much attention to cleantech in the last little while, it’s time to sit up and take notice.
Because post-Solyndra, cleantech has been quietly gaining momentum.
We had the chance to take a close look at the fundamentals of cleantech over the last two months in co-authoring a new (and free!) 38-page research report in conjunction with Oakland, Calif.-based advocacy group As You Sow and the Responsible Endowments Coalition of Brooklyn, New York. (more…)
Though Norway in June overtook Russia in total exports of natural gas to Europe, the balance of Russian gas to Europe comes through Ukraine, which itself is dependent upon Russia for 60% of its current gas consumption.
While Ukraine controls the transit of 90% of its gas to Europe, Russia is consistently trying to use its gas (more…)
United Nation experts are encouraging the Japanese government to better communicate contamination goals with the public but are otherwise very positive about the progress that has been made in the Fukushima Daiichi nuclear accident remediation efforts in Japan. The experts are from the International Atomic Energy Agency (more…)
One of the big questions about solar power is how to supply sun-driven electricity at times of peak demand. Demand spikes in the early morning, before the sun is high enough to hit solar panels, and in the early evening, when solar panels operate at only at half efficiency in the low light. Cost-effective storage has been a major issue to be solved. (more…)
The British government and the French state-controlled utility company, EDF Group, have agreed to build the U.K.’s first nuclear power plant in a generation. The new plant, to be built at Hinkley Point in southwest England, is part of the British government’s ongoing efforts to cut carbon emissions in half by the mid-2020s. (more…)
