Power Makes the World Go Round
There is no substitute for power. Where does this power come from? Oil, gas, coal, water, wind, solar, biomass, and nuclear. As we move ever forward in the development of clean energy our power needs are increasing every year and far outweigh the ability for water, solar, and wind to fully provide the requirements demanded of the global energy grid. Just the effort in reducing pollution by replacing gas-driven vehicles with electric will result in a huge uptick in demand. Where is the power coming from that recharges the batteries in these vehicles? From the power grid fueled by existing energy production.
