Is There Is Enough Water To Support India's Power Expansion?"Water in a coal-based power plant is heated and turned into steam for power. Power plants require a substantial amount of water for cooling purposes and for operations.

We use window treatments to help insulate the room against extreme heat and cold. We may use them to block light or direct light to one part of the room only.

Geothermal [in Greek: "geo" = earth/"therme" = heat] energy is the most logical choice for establishing "green" "base-load" power.

A thermal engineer is a professional who specializes in a complex field of engineering that focuses on thermodynamics, heat transfer, mass transfer, and fluid mechanics.

A Provo firm Thursday launched a project that could foreshadow the next revolution in renewable energy resources for Utah and the rest of the nation. Raser Technologies Inc. marked the completion of a 10-megawatt geothermal power plant with a ribbon-cutting ceremony at the Beaver County facility located in Thermo. It is the first commercial-scale facility to utilize a new technology that allows the plant to generate electricity using geothermal heated water that is at a much lower temperature than was previously possible, said John Fox, general manager of UTC Power Corp.

What better way to save the world than to start in your own back yard? That's what Doug Rempel is doing - one SIP at a time. Doug is currently building an entirely energy efficient home next to Lillooet Lake, in Pemberton, B.C. The home is "off the grid" which means everything, from the solar insulation panels (SIPS) to the architecture of the home - with window levels and patio ledges based on sun path charts - is created to heat and cool in the most natural way possible. There is no hydro power or natural gas. "Energy-efficiency is a career as well as a passion of mine," says Doug.

The development of geothermal energy in Australia is a step closer with the launch of an industry framework today. Geothermal energy is produced by harnessing the heat of so called 'hot rocks' buried kilometres underground. The framework has brought together industry, researchers and governments to work out how to make geothermal a genuine baseload power alternative.

Reporting from Reno -- Not far from the blinking casinos of this gambler's paradise lies what could be called the Biggest Little Power Plant in the World. Tucked into a few dusty acres across from a shopping mall, it uses steam heat from deep within the Earth's crust to generate electricity. Known as geothermal, the energy is clean, reliable and so abundant that this facility produces more than enough electricity to power every home in Reno, population 221,000.

The U.S. Department of Energy and the National Renewable Energy Laboratory have released the first technical support documents to show 50 percent energy savings in commercial retail buildings. The two reports provide recommendations on how to achieve 50 percent energy savings over the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standard 90.1-2004 in grocery stores and medium-sized retail buildings. Conducted by NREL's Commercial Buildings team, under the direction of DOE's Building Technologies Program, the studies support DOE's goal of producing market-ready, net-zero energy commercial buildings by 2025.

With fossil fuel prices escalating and countries searching for ways to reduce oil dependence and greenhouse gas emissions, capturing the earth's heat for power generation is garnering new attention. First begun in Larderello, Italy, in 1904, electricity generation using geothermal energy is now taking place in 24 countries, 5 of which use it to produce 15 percent or more of their total electricity. In the first half of 2008, total world installed geothermal power capacity passed 10,000 megawatts and now produces enough electricity to meet the needs of 60 million people, roughly the population of the United Kingdom. In 2010, capacity could increase to 13,500 megawatts across 46 countries-equivalent to 27 coal-fired power plants.

Cogeneration of electricity and heat is one of the most promising means of using existing technologies for sustainable ends, but it is also one of the most neglected and least understood. Cogeneration can dramatically increase energy efficiency, slash carbon emissions, and save money.

Researchers at the U.S. Department of Energy's Idaho National Laboratory say they have devised an inexpensive way to produce plastic sheets containing billions of nanoantennas that collect heat energy generated by the sun and other sources. They say this technology is the first step toward a solar energy collector that could be mass-produced on flexible materials.

A report by the group ForestEthics estimates that destroying forests to make paper for junk mail releases as much greenhouse gas pollution as 9 million cars. Another way to look at it: Junk mail produces as much pollution as seven U.S. states combined, or as much as heating 13 million homes each winter. While the estimates may or may not be accurate, the point is indisputable: Junk mail is a waste. (To most people, it's an annoying part of the trip to the mailbox, anyway.)

When the tobacco industry was feeling the heat from scientists who showed that smoking caused cancer, it took decisive action. It engaged in a decades-long public relations campaign to undermine the medical research and discredit the scientists. The aim was not to prove tobacco harmless but to cast doubt on the science.

WASHINGTON (May 29, 2008) - More than 1,700 of the nation's most prominent scientists and economists today released a joint statement calling on policymakers to require immediate, deep reductions in heat-trapping emissions that cause global warming. Issued just days before the Senate begins debate on the Lieberman-Warner climate bill, the statement marks the first time leading U.S. scientists and economists have joined together to make such an appeal.

One in four British homes could be fitted with solar heating equipment and 3,500 wind turbines could be erected across Britain within 12 years as part of a green energy revolution to be proposed by the government next week.

No one will be surprised that Greenpeace is against the construction of new nuclear power stations, but what some may find unusual is one of the solutions we are proposing to meet our energy needs and reduce our CO2 emissions - industrial CHP, or combined heat and power.

Parabolic troughs, one of which is shown here, have been around for 25 years, and the technology will be around for at least another 25. Parabolic troughs reflect sunlight to heat liquid carried through a tube above the troughs. That liquid is converted to steam, which drives a traditional electricity turbine.

British inventors have designed a washing machine that takes eco-friendliness to a new level: it uses just a single cup of water to wash a load of clothes. Instead of water the Xeros machine uses thousands of special plastic chips (about 44 pounds' worth) in each wash, and when that single cup of water is heated, these chips absorb the dirt-including tricky stuff like coffee and lipstick. The chips are removed when the wash ends, and can be reused up to 100 times. Though it's still in prototyping, the inventors are intending to commercialize their machine, and it may even hit the shops next year for a price similar to conventional machines.
