Developing renewable energy sources is the means to secure for safe future.

  1. 1. Developing Renewable Energy Sources Is The Means To Secure For Safe Future Sarbottam Silwal
  2. 2. Energy • It is the strength and vitality required for sustained physical or mental activit • It is an important aspect of every living organism • There are many different sources of energy that are naturally available throughout the world in different forms • Energy is measured in SI units of joules ( J )
  3. 3. categorization Depending with energy regeneration
  4. 4. Concerning on Renewable Sources • It is obtained from different natural sources • Main common sources are sunlight, wind, tides and geothermal • Statistics indicated it is approximate 16% of total global energy that is consumed on daily basis • One advantage about this form of energy is that it can be replaced and used continuously without becoming depleted
  5. 5. . Renewable sources of energy are mostly used in three different areas: electricity generation, heating by use of solar hot water and motor fuels through the use of renewable biofuels.
  6. 6. Advantages • Renewable sources of energy are renewable and easily regenerated. This is unlike fossil fuels which are perishable once used. • Renewable source of energy such as solar produce clean energy that does not pollute the environment. This is because no burning is required during usage of the energy. • Renewable sources of energy boost economic growth and increase job opportunities. This includes electrical energy which is used to run many industries
  7. 7. Advantages • Maintenance cost needed to install and use the renewable energy is relatively cheap. Solar energy can be trapped easily and used for domestic needs. • Most importantly, renewable energy are available everywhere throughout the world thus there is no chance of the sources becoming depleted in future. For example, solar energy is everywhere as the sun will always be there every day.
  8. 8. For Future • Using renewable sources of energy helps to create a healthier and green world • Non renewable sources Produce harmful green house gases which contribute global warming. Coal once burnt produces carbon dioxide harmful to the environment. • Once Non renewable sources are depleted they cannot be replaced making them expensive to obtain.
