What is the importance of energy resources? Give two examples each of conventional and

non-conventional sources of energy

Energy Resources are required  to make electricity, to heat our homes, to move our cars, and to manufacture all kinds of
products.

  • Renewable Resources- they are replenished in a short time. Renewable energy sources include biomass, geothermal energy, hydropower, solar energy and wind energy.
  • Non- Renewable Resources- the supply of these resources are limited. Petroleum, for example, was formed millions of years ago from the remains of ancient sea plants and animals. We cannot make more petroleum in a short time. It is thus very important to look towards the conservation of these resources.

Energy supply must be sustainable and diverse. And energy needs to be used more efficiently.

A sustainable energy supply, both in the short- and the long-term, is needed for promoting both economic development and people's quality of life, as well as protecting the environment.
We also need a greater diversification of energy resources - if we are largely dependent on one fuel source, we risk price rises and supply disruptions.
Energy is a precious resource which must be conserved. Improved energy efficiency, therefore, in our homes, factories and transport needs to be strongly encouraged.

Examples:-

Conventional (or usual) sources of energy (electricity) are coal, oil, wood, peat, uranium.

Non-conventional (or unusual) sources of energy include:
  • Solar power
  • Hydro-electric power (dams in rivers)
  • Wind power
  • Tidal power
  • Ocean wave power
  • Geothermal power (heat from deep under the ground)
  • Ocean thermal power (the difference in heat between shallow and deep water)
  • Biomass (burning of vegetation to stop it producing methane)
  • Biofuel (producing ethanol (petroleum) from plants

Thumbs up please....!!!!!

 importance of energy resources:

1. they are required for all activities i.e. for industrial as well as domestic uses.

2. in home they are mostly used for cooking and electricity.

3. enery resouces hava a major role in industries. energy resources are basic necessity for industries.

 

conventional: coal, petroluem etc.

non - conventional: solar energy , tidal energy , wind energy etc.

 

hope this helps u......
