Renewable Energy Explained

At least 29 U.S. states have set renewable portfolio standards—policies that mandate a certain percentage of energy from renewable sources. More than 100 cities worldwide now boast receiving at least 70 percent of their energy from renewable sources, and still others are making commitments to reach 100 percent.

Nonrenewable Energy

Nonrenewable energy comes from sources that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes. Most nonrenewable energy sources are fossil fuels: coal, petroleum, and natural gas. Carbon is the main element in fossil fuels. For this reason, the time period that fossil fuels formed (about 360-300 million ...
