There are many energy sources in the world we live. These resources include Natural gas, Oil, Coal, and Hydropower. But, not all energy sources can be renewable. These sources are difficult to replace by natural processes. These energy sources are often referred to as "non-renewable". Therefore, it is very important to find ways to replace them. Let's look at some examples.
Natural gas
The United States has a high natural gas consumption. Texas is the biggest user, using 52% natural gas to make electricity. Texas has large populations, commerce and industry. Therefore, natural gas is very important for Texas. California is next, but California uses 54% more natural gas than Texas. Natural gas is not renewable and it can be hard to store.
Oil
Many people believe that oil cannot be used as a renewable energy source. It has a high net energy yield but it can also have negative effects. Oil burning can contribute to global warming and cause pollution in the air. It is also a major cause of smog. The burning of oil in power plants, industrial plants, or cars is the main cause of pollution. When oil is burned it releases harmful toxins to the atmosphere. It also emits carbon dioxide, which is considered a greenhouse gas.
Coal
Coal is an energy source that cannot be used again. It takes many millions of years for coal to form. Coal is a solidified sedimentary rock that can be used to make combustible coal. It consists mainly of carbon and hydrocarbons. This fossil fuel comes mainly from the remains and remains of prehistoric creatures and plants. The fossil fuel family includes coal, which is used for heating, electricity production, transport, and transportation. Here are some facts about coal.
Hydropower
Hydropower is an older, non-renewable source of energy that can be used in electricity generation. Appleton, Wis., was home to the first ever hydroelectric dam. These dams were groundbreaking and quickly became a national trend. Famous dams in the West, such as the Hoover Dam, provided 40 percent of the country's electricity during the 1930s.
Nuclear energy
While nuclear energy has numerous benefits, it is a non renewable energy source. This is because the world's uranium supplies are very limited. 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 it won't regenerate unless the uranium source is changed.
Uranium
Although uranium is found in abundance in the earth's crust, the resource is not infinite. Uranium must be extracted, used, and disposed of. It is a fissile resource and produces no emissions. It is used in nuclear reactors to produce heat, which powers turbines and generates electricity. Unlike other fossil fuels like coal, uranium produces no toxic byproducts.
