Question

What is meant by renewable sources of energy? Give two examples of renewable sources of energy.

Answer 1

Hint: When it comes to energy resources, the issue of sustainability is always there. It's critical that resources offer enough energy to heat our homes, power our cities, and power our automobiles. However, it's equally crucial to think about how these resources can be used in the long run.

Complete answer:
Some resources are virtually inexhaustible. Renewable resources are those that can be replenished throughout time. Clean energy is produced by renewable resources, which means reduced pollution and greenhouse gas emissions, both of which contribute to climate change. Biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy are examples of renewable resources.

Biomass from plants or animals is referred to as biomass. This includes wood, sewage, and ethanol, among other things (which comes from corn or other plants). Because this biological material has absorbed energy from the Sun, it can be used as a source of energy.When this energy is burned, it is converted to heat energy.

Hydropower is one of the oldest renewable energy sources, with thousands of years of use.Hydroelectricity is now used in every state in the United States. The mechanical energy of flowing water is used to generate electricity in hydropower. Hydroelectric power plants generate energy by turning a turbine that is powered by the flow of rivers and streams.

Note: There are various drawbacks to utilising renewable resources. Renewable energy, for example, can be less reliable than nonrenewable energy, with seasonal or even daily fluctuations in output. Scientists, on the other hand, are constantly addressing these issues, attempting to increase the practicality and reliability of renewable energy.
