How (Not) to Run a Modern Society on Solar and Wind Power Alone


While the potential of wind and solar energy is more than sufficient to supply the electricity demand of industrial societies, these resources are only available intermittently. To ensure that supply always meets demand, a renewable power grid needs an oversized power generation and transmission capacity of up to ten times the peak demand. It also requires a balancing capacity of fossil fuel power plants, or its equivalent in energy storage.

Consequently, matching supply to demand at all times makes renewable power production a complex, slow, expensive and unsustainable undertaking. Yet, if we would adjust energy demand to the variable supply of solar and wind energy, a renewable power grid could be much more advantageous. Using wind and solar energy only when they're available is a traditional concept that modern technology can improve upon significantly.
 
the problem with "green" energy is its not really so green. They may greatly reduce atmospheric emissions of fossil fuels but simply move the footprint to another location usually the dirt and ecosystems. Want to increase global warming or grow your crops on toxic land... pick one! Who says wind and solar is a "renewable" energy?

How Green Are Those Solar Panels, Really?
 
Speaking of "green", and the inability of tens of millions of people to buy and use a normal wood stove for decades, I find it moronic that all the solar cells around here are currently covered with ash and soot from the forest fires. yea, go green

They're NOT covered in ash.... it's planet killin' carbon! Nice knowin' ya, goodbye cruel world.


OK, not really, you first..... buuuurrrrp!
