There are many types of energy available in the world that we live in. These include Oil, Natural gas, Coal, and hydropower. But, not all energy sources can be renewable. These energy sources are hard to replace with natural processes. These energy sources can be referred too as "nonrenewable". It is important to find a way to replace them. Let's take a look at some examples of these types of resources.
Natural gas
The U.S. has a large natural gas consumption. Texas is the biggest user, using 52% natural gas to make electricity. Texas is home to a large population and a lot of commerce. Natural gas is therefore important. California is next but California uses 54% fewer natural gas than Texas. But the issue with natural gas is that it is not renewable, and it is difficult to store it effectively.

Oil
Many people believe that oil is not a renewable energy source. Oil has a relatively high energy yield but can have adverse effects. Burning oil can result in air pollution and even contribute to global climate change. It is also a major cause of smog. It is caused by oil burning in power plants and industrial plants. When oil is burned, it releases harmful toxins into the atmosphere. It also emits carbon dioxide which is a greenhouse gases.
Coal
Coal is a non-renewable energy source that takes millions of years to create. Coal is a combustible sedimentary rock made up mostly of carbon and hydrocarbons. This fossil fuel was formed from the remains of prehistoric animals, plants, and plants. Coal is a fossil fuel and can be used to produce electricity, transport, or heat. Here are some facts regarding coal.
Hydropower
Hydropower, an old source of non-renewable power that can be used for electricity generation, is an example. Appleton, Wis. was the home of the first hydroelectric dam. The idea spread quickly across the country. Famous dams in the West, such as the Hoover Dam, provided 40 percent of the country's electricity during the 1930s.
Nuclear energy
Nuclear energy is an energy source that has many advantages, but it is also non-renewable. This is due in part to the limited amount of uranium available on earth. A source of uranium must be renewable if it is to be sustained for a significant amount of time. The U.S. Department of Energy classifies uranium as a non renewable energy source. This means that it cannot be regenerated unless its source changes.

Uranium
Although uranium is found in abundance in the earth's crust, the resource is not infinite. It must first be mined, then used, and finally disposed off. It is a fissile energy and produces no carbon emissions. When uranium is used in nuclear reactors, it produces heat that powers turbines, generating electricity. Uranium is not toxic like other fossil fuels.
