Importance of Renewable Energy Sources

  • Renewable energy sources are those that are inexhaustible and will never be depleted. They encompass:
    • Hydroelectric
    • Wave/tidal
    • Wind
    • Solar
    • Geothermal
    • Biomass/waste
  • Once established, except for biomass/waste, these sources do not release any greenhouse gases into the atmosphere.
  • While no emissions occur during their operation, greenhouse gases might be produced during their manufacturing, installation, and transportation processes.

Increase in renewable energy

  • Renewable energy plays an increasingly vital role in the global energy mix for several reasons:
  • Non-renewable fossil fuels are finite resources that will eventually be depleted, necessitating the need for alternative energy sources.
  • The utilization of non-renewable fuels poses significant environmental risks. When fossil fuels are burned, they emit greenhouse gases, contributing to climate change. Additionally, the release of sulfur dioxide can lead to acid rain.
  • The extraction processes involved in mining and drilling for fossil fuels can have devastating impacts on natural habitats and the environment as a whole.
  • Growing awareness of the detrimental effects of fossil fuel consumption has led to international pressure to decrease their usage.
  • Many countries are seeking to reduce their dependence on imported energy resources to enhance their energy security.
