Many sources can be used to generate energy resources. The Earth is the primary source of energy resources. These resources include wood, agricultural and waste materials, as well as energy crops. Landfill gas is another option. These resources are very varied and can need individual management. To address this issue, it is best to separate each resource.
Natural resources
Renewable resources are those that can be replenished. Nonrenewable resources, on the other hand, cannot be used after their stock is exhausted. Metals, for example, are nonrenewable because they cannot be replaced after they are mined. As the population grows, so does the demand for renewable energy. Even though fossil fuels are used for energy source since the late 1880s. Renewable resources are becoming increasingly available.
Natural fuels
One of the oldest sources for energy is natural fuels. While coal was a valuable source of energy for a long period, it is less common now that renewable energy sources are more cost-effective. Many countries are shifting away form fossil fuels in favor more renewable energy.
Oil
Oil can be used to power many industrial processes. But oil has its limitations. The first is oil's limited supply. The oil supply in the world is rapidly decreasing and oil prices are rising. Its adverse impact on our environment is another. Oil extraction pollutes the oceans and causes serious damage to marine life.
Hydroelectricity
Hydroelectricity has the potential to be an endless source of energy and is renewable. It works well in combination with other renewable resources such as solar power and wind energy. It's also one of most flexible forms for energy generation. It can be set up and taken down in just two minutes. This makes it an excellent choice to balance production levels throughout the day.
Bioenergy
Bioenergy can be used to produce electricity, heat and other energy resources. Around 2% global electricity generation was represented by the world's bioenergy capacities in 2016. They reached 110 gigawatts (GW). During the same period, capacity additions averaged about five to seven GW per year. Bioenergy is cost-effective and can provide a reliable source of renewable energy.
Nuclear energy
A renewable energy source, nuclear energy can be used to generate electricity and not emit any pollutants. It is used to power space exploration and sterilize medical equipment. It is also used to support clean air initiatives and combat climate change.
