Use of renewable enery as a solution for enegy crisis


Renewable energy is useful energy that is collected from renewable resources which are naturally replenished on a human timescale, including carbon neutral sources like sunlight, wind,rain,tides,waves, and geothermal heat. The term often also encompasses biomass as well, whose carbon neutral status is under debate.This type of energy source stands in contrast to fossil fuels which are being used far more quickly than they are being replenished

Renewable energy often provides energy in four important areas: electricity generation,air and water heating/cooling,transportation and rural (off-grid) energy services.

Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.

History of using renewable energy

Prior to the development of coal in the mid 19th century, nearly all energy used was renewable. Almost without a doubt the oldest known use of renewable energy, in the form of traditional biomass to fuel fires, dates from more than a million years ago. The use of biomass for fire did not become commonplace until many hundreds of thousands of years later.

The most popular renewable energy sources currently are:

· Solar energy

· Wind energy

· Hydro energy

· Tidal energy

· Geothermal energy

· Biomass energy

The future of renewable energy

As world population rises, so does the demand for energy in order to power our homes, businesses and communities. Innovation and expansion of renewable sources of energy is key to maintaining a sustainable level of energy and protect our planet from climate change

In the future, it’s expected that the number of renewable energy sources will continue to increase as we see an increase in demand for power. This will drive down the price of renewables – great for the planet, and great for our wallets.
