General provisions *Under an amendment in the American Recovery and Reinvestment Act of 2009, Section 406, authorizes loan guarantees for innovative technologies that avoid greenhouse gases, which might include advanced nuclear reactor designs, such as pebble bed modular reactors (PBMRs) as well as clean coal and renewable energy; *Increases the amount of biofuel (usually ethanol) [...]

Being carbon neutral is increasingly seen as good corporate or state social responsibility and a growing list of corporations, cities and states are announcing dates for when they intend to become fully neutral. Companies and organizations Some corporate examples include Dell, Google, HSBC, ING Group, PepsiCo, and Tesco., Under the leadership of Secretary-General Ban Ki-moon, [...]
The definition of an energy source is not rigorous. Anything that can provide energy to anything else can qualify. Wood in a stove is full of potential thermal energy; in a car, mechanical energy is acquired from the combustion of gasoline, and the combustion of coal is converted from thermal to mechanical, and then to [...]
The “soft energy path” assumes that energy is but a means to social ends, and is not an end in itself. Soft energy paths involve efficient use of energy, diversity of energy production methods (matched in scale and quality to end uses), and special reliance on co-generation and “soft energy technologies” such as solar energy, [...]
The Energy Savings Trust has estimated that micro-generation could provide a significantly increased proportion of the UK’s electricity demand by 2050 although only a fraction of this would come from renewable sources. The current Scottish output is negligible. In May 2006 the then Communities Minister Malcolm Chisholm launched a Planning Advice Note aimed at promoting [...]
The first traceable concepts of environmental designs focused primarily on solar heating, which began in Ancient Greece around 500 BCE. At the time, most of Greece had exhausted its supply of wood for fuel, leading architects to design houses that would capture the solar energy of the sun. The Greeks understood that the position of [...]
GRT Air Capture Device According to the Earth Institute at Columbia University, [http://www.grestech.com/ Global Research Technologies, LLC] has demonstrated a prototype device capable of capturing 10 tons of carbon dioxide per square meter per year; a device of 10 meters by 10 meters would be able to capture 1,000 tons per year. It is estimated [...]
Wind power in Romania has an installed capacity of 10 MW, up from the 3 MW installed capacity in 2006. Romania has a high wind power potential of around 14,000 MW and a power generating capacity of 23 TWh, but until 2007 there were no significant wind farms in operation. Other renewable energy The annual [...]
Roots of the movement The application of nuclear technology, both as a source of energy and as an instrument of war, has been controversial. Scientists and diplomats have debated nuclear weapons policy since before the atomic bombing of Hiroshima in 1945. The public became concerned about nuclear weapons testing from about 1954, following extensive nuclear [...]
Geothermal power requires no fuel (except for pumps), and is therefore immune to fuel cost fluctuations, but capital costs are significant. Drilling accounts for over half the costs, and exploration of deep resources entails significant risks. A typical well doublet (extraction and injection wells) in Nevada can support 4.5 megawatts (MW) and costs about $10& [...]
Cangrejal: This planned dam on the Rio Cangrejal near La Ceiba, with an associated 40 MW power plant, has attracted international criticism due to its potential environmental impact, including the flooding of rapids that are a well-known whitewater sports destination and attract many tourists * Patuca 3: The Patuca 3 dam on the Patuca River [...]
Geothermal power is considered to be sustainable because any projected heat extraction is small compared to the Earth’s heat content. The Earth has an internal heat content of 1031& joules (3·1015& TW·hr). About 20% of this is residual heat from planetary accretion, and the remainder is attributed to higher radioactive decay rates that existed in [...]
The Hirsch report made clear that an energy crisis is best averted by preparation. In 2008, solutions such as the Pickens Plan and the satirical in origin Paris Hilton energy plan suggest the growing public consciousness of the importance of mitigation. Energy policy may be reformed leading to greater energy intensity, for example in Iran [...]
A long-term, targeted and focused energy strategy has ensured that Denmark’s total energy consumption has not risen over the last 30 years despite the country’s strong economic growth and development. Today, renewable energy covers 14% of Denmark’s energy consumption and more than 28% of electricity production. Renewable energy in Denmark refers to energy produced on [...]
Hot springs have been used for bathing at least since paleolithic times. The oldest known spa is a stone pool on China’s Lisan mountain built in the Qin dynasty in the 3rd century BC, at the same site where the Huaqing Chi palace was later built. In the first century AD, Romans conquered ”Aquae Sulis”, [...]
