Renewable Energy Sources

"Title" America consumes a lot of energy every day. Only about 8% of US energy demand comes from renewable energy sources. This means that 92% of the country's energy resources will eventually run out. This problem has attracted public attention lately, and the attention of American people has shifted to renewable "green" energy resources. President Jimmy Carter (1977) states as follows. "In addition to preventing war, this (energy crisis) is the biggest challenge our country faces during our lifetime" (p.

Renewable energy sources include biomass, geothermal, hydraulic, sunlight, wind power and so on. They are called renewable energy because they are replenished in a short period of time. Every day the sun shines, the wind blows and the river flows. We mainly use renewable energy to generate electricity. Since electricity and hydrogen are secondary energy sources, they are different from other energy sources. Secondary Energy - Energy Carriers - Used to deliver energy in a format that is easy to store, transfer, and use. We must use a different energy source to make electricity and hydrogen. In the United States, coal is the most power source. Today, the cheapest way to get hydrogen is to separate hydrogen from natural gas, a renewable energy source. Hydrogen can also be separated from water and recrystallized, but hydrogen produced from these sources is currently too expensive to compete with other fuels.

Energy Profile Energy has been confirmed to be key for almost all household and industrial operations. There are two types of energy: renewable energy and non-renewable energy. Renewable energy refers to the type of natural supplement. These include sunlight, wind, ocean tides, waves, geothermal heat, and rain (Tiwari et al., 2012). On the other hand, non-renewable energy is a type that can not be self-regenerated.

Renewable energy is energy that is complemented continuously by natural processes. These resources are often referred to as alternative or renewable resources, as they are mainly fuels replacing traditional non-renewable fossil fuels. Fossil fuels such as oil and coal produce energy when burned but their supply is limited because it can not be replenished in a short enough time for human use. Renewable energy is beneficial compared to fossil fuels because it has very little negative environmental impact. In the past, they were too expensive to use extensively. However, this situation is changing. Many renewable energy sources are cost-effective and may even make a wise financial decision for homeowners, businesses and governments. In particular, solar energy is a good choice for owners who want to save money while reducing the environmental impact.
