Renewable Alternative Energy Resources – Advantages and Disadvantages

wind and solar energy as alternative renewable energy

INTRODUCTION

Renewable Sources: These are naturally occurring resources that get replenished over time. Examples are geothermal heat, tides, precipitation, wind, sunlight, waves, etc. The energy that is produced from renewable natural resources is called renewable energy. It also involves energy that is produced from a renewable resource such as biomass.

Non-Renewable Sources: These are natural resources that don’t get replenished quickly. Examples are fossil fuels. The energy that is produced from nonrenewable resources is called nonrenewable energy. Organic matter is transformed into natural gas or oil over time with increased temperature and pressure under the surface of Earth.

RENEWABLE ALTERNATIVE ENERGY SOURCES

Fossil fuel combustion releases carbon dioxide that is a greenhouse gas and causes global warming. Environmental pollution is increasing due to coal-fired power plants. Non-renewable energy resources are getting depleted due to overexploitation. There is a dire need for renewable alternative energy sources to reduce environmental pollution. Below five renewable alternative energy resources are mentioned.

1. Solar Energy: It is defined as the production of electricity by using energy from sunlight. It includes photovoltaics, solar power systems, etc. (Read: The Rise of Solar Energy in Pakistan)

2. Wind Power: It is defined as the production of electrical power by using wind energy. The wind provides mechanical power to wind turbines.

3. Geothermal Energy: It is defined as thermal energy that is produced and gets stored in the Earth’s crust naturally. It is produced as a result of radioactive decay. It includes hot springs, geysers, etc.

4. Hydropower: It is defined as the production of electricity by using fast-running water. The kinetic energy of water is transformed into mechanical energy to run power machines.

5. Bioenergy: It is defined as the production of energy by using biofuel or biomass. The organic matter transforms and stores sunlight into chemical energy. It includes yard waste, food waste, waste from crops, etc.

The table below is representing the advantages and disadvantages of alternative renewable energy sources.
