Energy is neither created nor destroyed — and yet the global demand for it continues to increase. But where does energy come from, and where does it go? Joshua M. Sneideman examines the many ways in which energy cycles through our planet, from the sun to our food chain to electricity and beyond.

*Fracking, Bottled Water Companies and Extreme Drought, are all having huge impacts on Our Water. ( **tinyurl.com/y3gpstue** ) Add California's water supply to your list of "things headed for imminent collapse." The state has only one year of reserves remaining, warns Jay Famiglietti, the senior water scientist at the NASA Jet Propulsion Laboratory at Caltech.*

*Great stuff! Nice work. The public really needs to see more of this. Have you heard anything about a new system called Optimal Future Energy Deployment ( **lovy.biz/qy48** )? I’ve heard some interesting things about it and my brother got some amazing results. I’ve also been searching for solutions to the problem of wind turbines killing birds and bats. Ultrasonic acoustics looks like a possible answer to saving bats, but I haven’t read anything lately about the best way to keep birds away from wind turbines. Have you heard anything?*

is nuclear energy more efficiant then others and is it the best energy available I think so cause solar, and wind cant match the production output of fossil fuels

Really well done video. I will be showing this to my 6th graders today as part of our unit on renewable and non-renewable energy sources. This video was great in explaining things very simply. Yes, I do wish nuclear energy and hydrogen fuel cells were mentioned. A possible video idea in the future would be to make a video on all the renewable and non-renewable energy sources and the pros and cons of each. Thank you again for a great educational piece. Kudos!

How to create cleaner coal - Emma A guide to the energy of the Earth - Joshua 2 days ago   05:54

It takes a lot of fuel to heat our homes, preserve our food, and power our gadgets. And for 40 percent of the world, cheap, plentiful coal gets the job done. But coal also releases pollutants into the air, causing environmental damage like acid rain and serious health problems. Can we create a cleaner version of coal? Emma Bryce details the three ways we might strip coal of its foul forces.
