Bloomberg U.S. Energy Policy Should Take a Lesson From Germany's Energiewende Bloomberg “Energiewende” may not be a household word in the United States today, but U.S. citizens and policymakers are likely to hear more about it.
Germany already gets nearly 25 percent of its electricity from renewable sources, up from just under 7 percent thirteen years ago. That is no small feat. Germany is a manufacturing powerhouse: It's the world's fifth largest economy and third largest exporter.
The oil crisis in the early 1970s forced Sweden to embark on a quest for alternative energy sources. In 1970, oil accounted for 77 percent of Sweden’s energy, but by 2003 that figure fell to 32 percent.
According to the energy committee of the Royal Swedish Academy of Sciences, there is growing concern among nations that global oil supplies are peaking and will soon become scarce, causing the price of oil to skyrocket. Committee members predict that a global economic recession could ensue, and Sweden is taking action to make its economy less vulnerable.
Most people have assumed that the UK does not have enough feasible pumped-storage potential for a renewable energy revolution to take place.
Energy is stored so that the excess electricity supply from intermittent technologies such as wind and solar can be consumed at different times. Nuclear reactors can operate at full capacity at night when the demand for electricity is low as the energy is stored. For example, around 9% of Japan’s electricity generation capacity is pumped-storage as Japan once relied heavily on nuclear power.
The WINDHUNTER SYSTEM concept is an offshore, floating system that uses several wind turbines for power output to produce hydrogen by electrolyzing water. This continuously manned, safe and stable system will be easily maintained on-board while relocating to the best wind conditions for the wind turbines. The produced hydrogen gas may be compressed and stored as gas or liquefied and placed in insulated tanks. The compressed or liquefied hydrogen may be transferred by helicopter, surface ships or by other means.

“The best outcome would be, in five years, to have a new catalytic process which can make gasoline, diesel, and jet fuel at a price range that is better than, or competitive with, the cost of existing fuels,”
Happy New Year! Parties have already started all over the world. It’s already 2013 in Sydney, Australia, where fireworks exploded over the Sydney Harbour Bridge and Sydney Opera House to ring in the New Year to the delight of more than 1.5 million spectators today. "Our mission is to provide our customers with green energy at a low cost, furthermore, to help them..."
An international team of chemists, physicists and engineers have developed a new type of lightweight, flexible solar cells that could revolutionize the way we use renewable energy. Join us on twitter https://twitter.com/UtilityTreeInc
Saudi Arabia plans to produce electricity from its first nuclear plant by 2020 and begin operating a solar farm by 2015, said an official at the agency developing the country’s renewable energy program. Join the conversation on Twitter http://goo.gl/EGEbU
Norway, along with many other northern European countries, has built a network of co-generation plants that produce heat and electricity from recycled waste.
It’s really not as bizarre as it seems. Norway, along with many other northern European countries, has built a network of cogeneration plants that produce heat and electricity from recycled waste. Referred to as waste-to-energy facilities, the process is relatively simple. Garbage is burned in a portion of the facility, creating steam, ash and flue gases. The facility collects the steam and uses it to turn turbines, which generates the electricity used throughout much of the country. The ash is trucked away to a landfill, while the remaining gases are either filtered and dispersed into the atmosphere, or collected and used for additional products like biofuel.
Coal accounts for a vastly larger chunk of electricity production than solar. But industry reports suggest there are more solar employees than coal miners in the U.S.
“America has more solar workers than coal miners,” declared a CNN report in late April that summarized a survey done by the Solar Foundation, a nonprofit research and advocacy group. The National Solar Jobs Census, released in November 2012, found that there were 119,016 “solar workers,” meaning employees “who spend at least 50% of their time supporting solar-related activities.”
A bid to roll back or repeal state Renewable Portfolio Standard (RPS) requirements is getting traction, including in Arizona, North Carolina, Ohio and Texas.
The Environmental Defense Fund’s (EDF) Marita Mirzatuny calls their tactics “sneaky.” Heartland’s energy senior fellow, James Taylor, asserts the efforts are living up to the simple logic of ALEC’s proposed “Electricity Freedom Act” in those and other states.
A surprising aerodynamic innovation in wind turbine design called the 'wind lens' could triple the output of a typical wind turbine, making it less costly than nuclear power.
The International Clean Energy Analysis (ICEA) gateway estimates that the U.S. possesses 2.2 million km2 of high wind potential (Class 3-7 winds) — about 850,000 square miles of land that could yield high levels of wind energy. This makes the U.S. something of a Saudi Arabia for wind energy, ranked third in the world for total wind energy potential.
Arup Associates’ zero-carbon stadium for the 2022 FIFA World Cup Qatar Showcase has been honored with the World Architecture News’ 2012 Engineering Award.
The 500-seat zero-carbon exemplar stadium is a football stadium like no other. It is a proof-of-concept for innovative cooling and climate control technologies and a development platform to refine these technologies for application across Qatar and potentially across all arid regions.
Last year was officially the hottest ever recorded for the lower-48 states.
Scientists at the National Oceanic and Atmospheric tallied weather and temperature data for 2012, and found that the year was both the warmest and the second-most extreme for weather ever recorded for the contiguous U.S.

There is much meaning behind the name Community Power. It does not only refer to electrical power generated by a community; it also implies individual and community empowerment.
Community Power enables individuals to take steps towards the betterment of the environment, their communities, and also their personal finances. It also enables these individuals to gather for a common purpose and achieve something extraordinary, as a community. This is where true economic, environmental and social sustainability lies. Through igniting individual behaviour change and community solidarity, Community Power starts an empowering process that enables communities to provide local solutions to their local needs for the long term.
BREEAM is the world’s foremost environmental assessment method and rating system for buildings, with 200,000 buildings certified and around a million registered for assessment since it was first launched in 1990.
The largest commercial office in Manchester has now become the highest scoring BREEAM ‘Outstanding’ building in the UK with a score of 95.32%.
Designed by 3DReid, The Co-operative Group’s new £115 million low-energy, highly sustainable headquarters brings their 3,500 staff under one roof in a spectacular 500,000 square foot building.
The building, known as 1 Angel Square, has been designed to deliver a 50 per cent reduction in energy consumption compared to The Co-operative’s current Manchester complex and an 80 per cent reduction in carbon. This will lead to operating costs being lowered by up to 30 per cent...
