Energy resources can be obtained from many sources. The Earth is the primary source of energy resources. These resources can be wood, agricultural waste, or energy crops. Landfill gas is another option. These resources can be very diverse and require individual management. It is possible to manage each resource independently to solve this problem.
Natural resources
Renewable resources are those which can be replenished. However, nonrenewable resource cannot be used up once their stock has been exhausted. Metals, such as iron, are not renewable because they cannot be remined. With increasing human populations, there is an increased demand for renewable resources. Even though fossil fuels are used for energy source since the late 1880s. Renewable resources are becoming increasingly available.
Natural fuels
Natural fuels are among the oldest sources to energy. It was an important source of energy for centuries, but is becoming less popular as more renewable sources of energy are available at lower prices. However, many countries are shifting away from fossil fuels in favor of more renewable sources.
Oil
Oil is a renewable energy resource that can be used for a variety of industrial processes. But, oil does have its disadvantages. The first is its limited supply. The world's oil reserves are rapidly depleting, and the price of oil is continually rising. The environment is also a disadvantage. The oil extraction causes significant damage to marine life and pollutes the waters around the globe.
Hydroelectricity
Hydroelectricity has the potential to be an endless source of energy and is renewable. It can be used in conjunction with other renewable energy resources like wind and solar power. It is also one of the most flexible types of energy generation. It can be set up and taken down in just two minutes. This makes it an ideal choice for managing production levels during the day.
Bioenergy
Bioenergy can be used to produce electricity, heat and other energy resources. In 2016, the world's bioenergy capacity reached about 110 gigawatts (GW), accounting for around 2% of total global electricity generation. During this same time period, capacity additions averaged between five to seven GW each year. Bioenergy is affordable and a great resource to meet demand for renewable power.
Nuclear energy
Nuclear energy is a renewable energy source that can generate electricity without emitting pollutants. It can be used to power space exploration, sterilize medical equipment, provide potable water through desalination and produce radioisotopes to treat cancer. It is also used to support clean air initiatives and combat climate change.
