Environment on Earth

                                                                                                                                                                                                                                                               The word geothermal comes from the Greek words geo (earth) and thermal (heat). So, geothermal energy is heat from within the earth. We can use the steam and hot water produced inside the earth to heat buildings or generate electricity. Geothermal energy is a renewable energy source because the water is replenished by rainfall […]

 
A wind farm is a group of wind turbines in the same location used for production of electric power. Individual turbines are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network. At a substation, this medium-voltage electrical current is increased in voltage with a transformer for connection to the high […]

The House of Representatives passed legislation extending billions of dollars in tax credits for the solar, wind and biodiesel industries, ending months of uncertainty for renewable energy companies.
The House voted 263 to 171 in favor of the tax breaks as a part of the $700 billion bailout package for Wall Street. This package was overwhelmingly passed by […]

Solar lights and other solar home products are, indeed, environmentally friendly. But you do not need to consider yourself an environmentalist to realize the benefits of using solar powered products.

What are some other benefits of solar powered home products? Well, when you use solar home items, your electricity bills will go down. Why pay outrageous […]

Spain’s government said its new and less generous subsidy scheme, due to take effect shortly, foresees solar power plants reaching a capacity of 3,000 megawatts by 2010, or about double the present total.
Industry Minister Miguel Sebastian added, in testimony to the Senate, that the government expected the capacity of solar panels to expand to 10,000 […]

What is Small Scale Hydro?
Harnessing the power of water represents one of the oldest renewable energies in the history of mankind; firstly to irrigate land and to power mills for more than 2,000 years, but more recently to generate electricity also. Therefore it is a mature and proven technology.Small scale hydro power, often called micro […]

India will host the next Live Earth concert to raise funds for lighting homes with solar energy in places where people do not have access to electricity, organizers said.
The December event will see rocker Jon Bon Jovi and Bollywood’s biggest superstar, Amitabh Bachchan share the stage, and is described by organizers as one of the […]

The slow ripening of India?s biofuel industry
OUTSIDE his village in the Indian state of Chhattisgarh, Sudarshan Dhrube inspects a field of jatropha, planted in rust-red soils, heavy with iron. His village is growing the shrub under the watchful eye of D1-BP Fuel Crops, a joint venture between D1 Oils, a British biofuels firm, and BP, […]

Are We Overlooking Some of the World’s Sustainable Energy Fuels?
Ever since humans first huddled around a fire for warmth, people have burned logs, straw, wood and animal waste–otherwise known as biomass–to create energy. Indeed, throughout most of history, these crude forms of fuel answered the world’s energy needs. Only after the industrial age matured did […]

 
Wind energy system operations do not generate air or water emissions and do not produce hazardous waste. Nor do they deplete natural resources such as coal, oil, or gas, or cause environmental damage through resource extraction and transportation, or require significant amounts of water during operation. Wind’s pollution-free electricity can help reduce the environmental damage […]
