Around the Sky in 80 Kilowatts: Edmonds’ Flying Dynamo
It would take a stony hearted environmentalist not to appreciate the uplifting sight of hot air balloons floating in the air. But it could be argued that our oldest flying devices are vehicles for environmental harm given the amount of propane they consume. Now, though, a solar powered hot air balloon has been developed that far from burning up will actually generate energy by working as a giant engine.

Tuesday, December 16, 2008
Assuming that demand remains constant, oil reserves can cover global energy needs for no more than 40 years. Energy crunch is imminent unless alternative sources are deployed. Among renewable energy technologies, photovoltaics is currently enjoying the largest growth rate. While the solar energy absorbed by the Earth's surface in one hour is more than the energy used worldwide in a whole year, solar panels account for only 0.0008% of total energy consumption. But dauntless scientists are working steadily towards resolving such absurdities.

Wednesday, August 20, 2008
Just when we thought there were no more new fandangled ways of deriving energy from our shriveling planet, Australia comes up trumps. Scientists there believe untapped geothermal energy locked in three miles below the Earth’s surface is a worthwhile and completely sustainable alternative to using fossil fuels.

Monday, August 18, 2008
With all the concern about ongoing climate change and the need to conserve our environment, it seems like even financial institutions are becoming more responsive towards the green aspirations of their customers. So with a raft of new credit products, not just in the United States, but also in Europe and Asia, can we shop our way to a cleaner planet?

Monday, August 18, 2008
A team at Worcester Polytechnic Institue (WPI) have discovered a way of using the heat-absorbing properties of tarmac for an alternative energy source. Scientists are developing a solar collector which uses asphalt, potentially turning roads and parking lots into unique sources of electricity and hot water.

Sunday, January 6, 2008
From the “Wait a second. What?” files comes the story of Norway’s failing attempt to fight global warming by providing offshore gas and oil rigs with clean electricity. Photo via NASA Norway has been attempting to fight global warming by, among other ways, providing rigs drilling for oil and [...]

Friday, January 4, 2008
New technology means solar power could one day provide all the world’s energy needs – but governments must do their bit. Until a few years ago the suggestion that solar power might provide the answer to the intertwined problems of long term energy security and climate change would [...]
