US billions to support alternative energy
As the White House considers curtailing subsidies to traditional domestic energy suppliers, its support of alternative energy has soared.
A new report from the Department of Energy shows that subsidies to the solar and wind industries skyrocketed 626 and 946 percent, respectively, between 2007 and 2010. Total subsidies to these industries rose from $5.1 billion to $14.67 billion in that period, reports CNSNews.com.
In April, President Barack Obama reiterated his call for an end to subsidies Read more [...]
How to build your own wind turbine
Wind energy is both green and fun, so the idea of building one's own wind turbine is a good one. The following will give you an idea of what is involved.
Wind energy on a large scale is now competitive with other sources of electricity on a commercial scale. However, small domestic-sized wind turbines have not yet reached this point. The wind is free, but small wind turbines are expensive in relation to what they produce, and cannot realistically compete with mains electricity. Building your own Read more [...]
China to lead world in alternative energy
In just over a decade China is expected to become the world's largest producer and consumer of alternative energy, according to experts.
China's installed wind capacity has doubled in each of the past four years.
In addition, in just a little over four years, a mix of government and foreign investment has transformed the Chinesport city of Tianjin city into the global manufacturing hub of the world's wind power industry.
The country also has one third of the global solar panel market.

Taiwan invests heavily in alternative energy
Taiwan is to invest $1.4 billion in the island's domestic renewable energy sector, its government said today, in a move it says will help the sector grow nearly eight-fold by 2015.
"The green energy sector can turn Taiwan into a major power in energy technology and production, as well as provide the creation of green jobs," Taiwan's Premier Liu Chao-shiuan said in a statement.
The statement did not say over what period the investment would be made. Read more [...]
Solar panels do not need sun
Householders convinced that the UK does not have enough sunshine to effectively use solar panels are 'wrong', according to a domestic solar panel advisor.
The UK energy advisor Heat my Home has explained that the panels operate on solar radiation not sun rays and the UK gets enough of this to run solar.
Stuart Lovatt of Heat my Home said: "One unique selling point with solar is the longevity. A good quality system will easily last 30 years, so the long-term benefits of solar are obvious.
"How Read more [...]
Green Investments Set To Grow
Investments in green energy are set to rise says Ethical Corporation magazine.
It argues that the impact of climate change will alter the shape of the global economy over the coming years resulting in an expanding environmental technologies sector that will provide both attractive and long term investment opportunities for global investors.
A decade ago very few environmental technology investments were available for investors, other than those from a small number of pioneers specialising Read more [...]
California’s First “Power Tower”
Fascinating article in Scientific American reports how mirrors are harnessing the sun to generate electricity in California.
In southern California's Antelope Valley, 24,000 silver-bright mirrors have been positioned to reflect light on two 50-meter-tall towers. And at 11:08 A.M. local time Wednesday, this concentrated light heated steam in those towers to turn a turbine— the first "power towers" in the U.S. to convert the sun's heat into electricity for commercial use.
Dubbed Read more [...]
Home Solar Panels – How do they work?
Regardless of whether you choose clunky roof panels or integrated tiles, the basic principle of solar panels is the same.
Solar panels are made up of a series of photovoltaic cells, consisting of layers of a semi-conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers causing electricity to flow. The more intense the light, the more electricity you generate - but remember, it's light and not heat that matters, so you're not totally at Read more [...]
Supermarket Burns Meat for Electricity
UK supermarket chain Tesco has announced that it is sending its waste meat to be converted into renewable energy for British homes.
The retailer has proudly revealed that it is recycling all of its meat waste to heat and electricity, stating that the 5,000 tonnes of out-of-date meat that it sends to biomass plants will generate 2,500 Mega Watt Hours of renewable energy each year – enough to power more than 600 homes for a year.
But the innovative scheme has come under attack from vegetarians.The Read more [...]
Wave Power – Exciting New Technology Development
A new exciting technology to harness the power of waves and turn it into green energy was announced this week.
A giant machine called' Oyster' is being installed on the seabed of the Atlantic Ocan off Scotland’s Orkney Islands.
This autumn Oyster it will undergo demonstration trials to prove whether its innovative technology could lead to a commercial source of renewable energy for use in seashores around the world.
In contrast to many other wave power devices, Oyster uses hydraulic Read more [...]
