How Long Can You Power a Light Bulb With Two Pounds of Fuel?
One of the most important concepts in energy policy is understanding energy density, or how much energy can be extracted from a certain quantity of fuel. Solar and wind power are the least energy dense sources of power. They require huge amounts of land to produce small amounts of energy. Wood, or biomass, is more dense than wind or solar, coal is more energy dense than wood, oil is more energy dense than coal, and uranium puts all of these other sources to shame.
This is why wind and solar are the energy past, fossil fuels are the energy present, and nuclear power is probably the future. Enjoy this video below from Generation Atomic, a nuclear power advocacy organization.
