But where does solar energy and renewable sources and everything else -- where does it all fit in.

Green Lighting - Whirlwind Tour of Global Energy Consumption You may have ezra about solar energy (photovoltaic cells and the three types of solar thermal power plants. And we'll wind it up with a picture of the last 400,000 years where we quickly examine the question. We know that start cranking up in the 1800s, as the Industrial Revolution went into high-tech growth mode.

Graphs showing the emissions are nearly vertical for the last 50 years, it went from 1500 to 8000 (433% increase).

Back then, the planet could more easily absorb the emissions.The problem isn't that we're not emitting carbon at the same eustace as before. Let's go on a whirlwind journey of renewable energy, showing you views from 100,000 feet, then region by region, then showing you where renewable energy sources fit into the US consumption picture, and compare that to the rest of the world. It's that, just that, like a landfill, we're running out of room in the environment.
