While many of us might use electricity in our homes, that is only possible still due to the burning of coal in most places. Yet we’ve already proven that hydroelectric and nuclear energy are both possible and can be more widespread in the United States. Places like Norway make most of their money through exporting oil but happen to be the “cleanest” nation on Earth. Why? They use wind energy to power most of their cities. Solar energy has also proven to be valuable along with geothermal. Power grids can be hacked and altered, and power plants among other things are only bad for the environment. Why are we not taking advantage of these renewables? Simple, it’s a political thing. Oil, Gas, and Power Companies will lose money when we move in this direction and they have money to pay politicians.
