Urgent Need for Renewable Energy
Urgent need for renewable energy
Introduction
In today’s world the most important thing human’s need is electricity. Without electricity most of the modern equipment would not work. Similarly fuel is needed to power transportation devices. Natural recourses such as coal, oil and natural gas are the basis for producing energy for all kinds of devices. Due to the extensive use of these resources they now face extinction. These resources are classified as non-renewable resources. In this report we will discuss different types of resources which can be used as a replacement for producing sustainable energy and also the effects on the environment by burning the carbon based resources.
Renewable Energy
Renewable energy is energy which is derived from natural resources such as the sun, wind, tides, streams, rivers, biomass etc. Renewable energy is naturally replenished; it is sustainable energy and does not harm the environment. About 19% of the world’s electricity requirements are met by renewably energy. The different types of renewable energy are:
Solar Energy
Solar energy is obtained from the sun. Sun is a source of light and heat for all living things. It provides energy for photosynthesis, the process of plants creating oxygen. Solar energy can be harnessed and converted to electricity by using solar panels. Sun is also directly or indirectly responsible for most forms of renewable energy requirements, for example – heat causes wind which intern causes tidal energy. Sunlight causes tree growth some of which contribute for biomass energy.
Hydropower
Hydropower is obtained from the force of water flowing downstream. Water is continuously recycled by the environmental cycle of precipitation and evaporation. This cycle cause water to evaporate and fall back down to earth in the form of rain which makes the rivers flow. This water is also stored in dams which are used all around the world to generate electricity by turbines and generators. Also energy can be
