Protests against Tar Sand Oil in U.S.

Hundreds protest outside the White House in an attempt to stop U.S. President Barack Obama from approving the Keystone XL pipeline, which would be running right through the middle of U.S. extending from Canada to the Gulf of Mexico.

The pipeline in Alberta, Canada has already contaminated water bodies and people downstream these water sources have developed health related problems. For this reason, many scientists, environmentalists and citizens are protesting against signing of the pipeline construction deal. In fact the EPA has given the Keystone pipeline a failing grade and has called for a final review before the actual decision to support the dirty oil is taken.

Clean tech investor summit 2011: Nuclear energy

In January of 2006, Ralph Cavanagh and Peter Schwartz had an intellectual, inspiring, and heated conversation exploring the pros and cons of nuclear power at the Herbst Theater in San Francisco. Now, five years later, we are bringing them together again for a conversation as important as ever. Is nuclear power required to meet the challenges of climate change and potential planetary collapse? Or are there better pathways, is it too expensive, and is it quite literally, explosive? Ron Pernick, of Clean Edge and the Clean-Tech Investor Summit, will moderate this important and timely conversation.

The Energy Challenge and the Case for Fusion

Chris Llewellyn Smith, Vice President of the Royal Society and Visiting Professor at Oxford, discusses the advantages of fusion power for meeting the future energy needs of a still growing and modernizing world population with special emphasis on the technical challenges of tokamak fusion facilities, in particular the ITER project.

300 year of fossil fuels in 300 seconds

Fossil fuels have powered human growth and ingenuity for centuries. Now that were reaching the end of cheap and abundant oil and coal supplies, were in for an exciting ride. While theres a real risk that well fall off a cliff, theres still time to control our transition to a post-carbon future.
