Is algae fuel a viable alternative to oil based fuels? Well some bright dudes in California think so.
A dust track in California. An easy ride for the world’s latest endurance motorbike. Like any off-road machine, it’s fast, it’s tough and a ton of fun… But this bike is like no other … ….and nor is it’s rider, marine biologist Christian Gustavson.
“So my main interest is taking technology from the lab literally to the street. This bike is one of the most efficient motorcycles Read more [...]
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 Read more [...]
Plans for a massive expansion of renewable energy in Britain will cost families an average of £400 a year each, a report warned last night.
It accuses Energy Secretary Chris Huhne of ‘misleading’ the public by suggesting energy costs could be lower as a result of the Government’s drive for green power.
It said official estimates had grossly underestimated the impact on families by leaving out much of the huge taxpayer subsidy for wind farms and other forms of renewable energy.
The Read more [...]
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 [...]
Offshore wind farms cost twice as much to produce energy in the as coal-fired powered stations a UK report has warned.
Costs of building sites at sea have doubled in the past 5 years due to rising steel prices and the weak pound according to a report form the UK Energy Research Centre.
Could urine could be the next big alternative energy source? Two researchers at Heriot-Watt University in Edinburgh believe it can.
Shanwen Tao and Rong Lan, are developing a urine fuel cell.
Urine could constitute a much safer solution than hydrogen, much cleaner and non-toxic than methanol and could offer an abundant source of energy… from obvious reasons.
“We’re only at prototype stage at present, but if this renewable material can be used as a commercially viable and environmentally Read more [...]
With the opening of the Thanet Wind Farm off the coast of England the UK is now the world’s largest producer of wind energy.
The Thanet Wind Farm started sending power to the UK electric grid last week. It sits, at its closest, about 12 kilometers (7.5 miles) off the shore of Foreness Point, which is located at the most eastern part of Kent, England.
The $1.2 billion farm has 100 V90 wind turbines that have a total capacity of 300 MW. It creates enough power for 200,000 homes.
The UK’s Read more [...]
A device out of Stanford University is promising to revolutionise solar panel technology by being able to harness the power of both light and heat.
Scientists have always used both light and heat from the sun to produce energy, however, they hadn't yet discovered a way to efficiently utilize both simultaneously - until now!
Most accountable renewable energy invokes the following: *Solar Radiation *Wind Power *Wave Power *Hydroelectricity *Biomass And only a fraction of the radiation gathered Read more [...]
Installing solar panels or a wind turbine can be a very good investment in the UK thanks to the feed in tariffs which pay householders a tax-free, index linked income for the energy they produce, providing over a 10% annual return.
The tariffs pay up to 41.3p for every 1kWh of electricity produced using solar panels and an extra 3p per unit on top for any surplus electricity sold back to the grid.
The average cost of home solar panel installation is £14,000.
From this outlay, Ownenergy, Read more [...]
A sycamore seed design may be set to revolutionize the wind power industry.
British engineers have designed a giant wind turbine called the Aerogenerator that would rotate on its axis mimicking the way sycamore seeds fly.
The Aerogenerator has two arms coming out of its base to form a V-shape, with rigid "sails" mounted along their length. The arms act like aerofoils as the wind passes over, helping to generate lift.
It would measure nearly 900 feet from tip to tip and could generate Read more [...]
