What are the Sources of Renewable Energy?
Solar, wind, hydro, tidal, geothermal, and biomass are the sources of renewable energy.
- Solar energy is the most abundant source of renewable energy. The amount of solar energy that the earth receives in one hour is more than the planet’s total energy requirements for a whole year.
Solar energy is used to grow crops, stay warm, and dry food for thousands of years. In recent days, solar energy can also generate electricity, heat water, and indoor space.
- In ancient days wind energy was used to move ships; now, it generates electricity. Tidal energy can generate electricity.
- Hydro energy can generate electricity, and it is the largest renewable energy source for electricity in the United States.
- Biomass is organic material from plants and animals. When the biomass is burnt, it releases chemical energy that can generate electricity.
- Geothermal energy is the hydrothermal resource obtained from hot underground water pumped through a turbine to generate electricity.
What are the Advantages of Renewable Energy?
Renewable energy never runs out, and the technologies require less overall maintenance. Renewable energy generation sources are harmless to human health and the environment. They can help save money in the long term.
What are the Disadvantages of Renewable Energy?
Renewable energy technologies have a higher upfront cost. The resources aren’t all day and year-round. Because of the intermittency of some of the resources, there is a dire need for expensive energy storage.
