Maintaining a diverse fleet of power plants in California and taking advantage of the complementary nature of wind and solar power are two of the findings in a renewables portfolio standard (RPS) integration study recently released by the California Independent System Operator Corporation (ISO).
?This study provides a thorough analysis of the capability of the power grid to effectively manage an oncoming wave of highly intermittent energy resources and confirms the ISO is ready to manage the grid reliably under 20 percent RPS?
The ISO and its study partners, including GE Energy Consulting, gained insights about grid dynamics through the ?Integration of Renewable Resources?Operational Requirements and Generation Fleet Capability at 20% RPS.? The study assumes California will add 2,246 megawatts of solar and 6,686 megawatts of wind resources by 2012.
Northern Ireland just outlined how it hopes to get 40% of its electricity from renewable sources by 2020 and, apparently not to be outdone, First Minister of Scotland Alex Salmond thinks that’s not an ambitious enough target. Speaking to Reuters, Salmond said Scotland should be able to produce 100% its electricity from low-carbon sources by 2025.
A new report by Oceana outlines, as previous studies have done, just how bountiful the offshore wind power potential of the Atlantic coast of the United States is. While it varies from state to state, a handful of states could generate more electricity than they need, and more could supply a large part of their demand. Overall, offshore wind could generate more power than than the economically recoverable oil and gas reserves in the same locations.
Big oil companies and other special interests have spent millions of dollars in lobbying and campaign contributions to defeat clean energy and global warming legislation, according to a new analysis released Monday by the Center for American Progress Action Fund.
The study ?Dirty Money? found that the top 35 spending companies and trade associations invested more than $500 million in lobbying and campaign contributions from January 2009 to June 2010 to defeat clean energy legislation.
Aviation emissions contribute to this health problem, according to a new study that suggests that airplanes flying at a cruise altitude of around 35,000 feet emit pollutants that contribute to about 8,000 deaths per year globally.
They’re not as photogenic as pandas, nor as captivating as tigers: among conservationists, plants have tended to attract rather less attention than animals. That could start to change with the publication this week of the first list of extinction risks for the world’s plants.
The Sampled Red List Index for Plants indicates that 22 per cent of all wild plant species face extinction, comparable to the figure for mammals (21 per cent) and higher than that for birds (12 per cent). Of the threatened plant species, 63 per cent are found in tropical rainforest areas which could soon be cleared.
A group of businesses including British Airways, BT and The Co-operative as well as NGOs and MPs have issued a statement saying the GIB must be designed with a clear picture of the low carbon economy wants to achieve and over what timeframe.
It said the government must ensure the GIB is sufficiently capitalised by at least ?4bn-6bn over the next four years.
Using a massive 8,400-kilometer-wide (5,220-mile-wide) solar sail to harvest the power in solar wind, the team hopes their concept could generate 1 billion billion gigawatts of power, far more power than humanity needs — if they can get that power back to Earth.
Time is running out to register for the Carbon Reduction Commitment (CRC) Energy Efficiency scheme.
Businesses have until September 30 to register for the CRC, the mandatory scheme to reduce the carbon emissions and improve the energy efficiency of UK businesses and organisations.
Inside GE, Ecomagination is deemed a success, so much so that it has spawned a sister initiative (if you can spawn a sister) called Healthymagination, focused on profitably creating better health for more people. GE says that it expects Ecomagination product revenues to grow at twice the rate of GE’s overall revenue between now and 2015.
The logic behind both initiatives is simple, Bob noted. Big global problems demand big solutions from big companies. GE prides itself on “tackling the world’s most complex and pressing problems,” as chief executive Jeff Immelt writes in the report.
The trouble is, the payoff for GE’s shareholders have been disappointing. I didn’t realize just how disappointing until I put together this chart comparing GE’s stock-price performance to the S&P500 and to a couple of its conglomerate competitors, Siemens and United Technologies.
The Transaction Processing Performance Council (TPC) has added a power efficiency metric, TPC-Energy, to its ongoing roundups of speedy transactional processing systems. Hewlett-Packard is the first participant to use the new TPC-Energy specification, submitting benchmark results of four of its systems.
“Energy is an increasing factor in the total cost of ownership” for many organisations, said Karl Huppler, chairman of the TPC. The new benchmark will allow an organisation to judge how energy efficient systems are, as judged by watts per performance.
A new report by the Green Scissors Campaign details some $200 billion worth of yearly US government subsidies that the coalition says are “wasteful to taxpayers, harmful to the environment and bad for consumers.” Green Scissors 2010 [PDF] covers four broad areas in which these subsidies occur– energy, agriculture and biofuels, infrastructure, and public lands.
British, American and Norwegian engineers are in a race to design and build the holy grail of wind turbines – giant, 10MW offshore machines twice the size and power of anything seen before – that could transform the global energy market because of their economies of scale.
A new WDM/PLATFORM report released today finds that transforming the Royal Bank of Scotland into the Green Investment Bank would kick start the green energy revolution. ?The research, by former Pricewaterhouse Coopers consultant, James Leaton, finds that it would bring 50,000 new green jobs a year, boost the UK economy, reduce the UK’s carbon emissions and improve international competitiveness – whilst not increasing the budget deficit.
The warming temperatures of the ocean are problematic for many species, but especially worrisome is the impact hotter water has on cornerstone species upon which many other marine animals rely. Usually we hear about changes in ocean temperature impacting coral reefs, but now scientists are finding that across the globe, phytoplankton — the food for zooplankton which is food for many other ocean species — is in decline, and that will have massive impacts for not just the marine food chain but ocean systems on the whole.
