Wind is a beneficial resource because it is a no-emissions energy source, so it produces no air or water pollution. Its operational costs are pretty low as wind is free. Wind energy is very efficient. Wind power is considered as a renewable energy resource. This means that the power generated from wind is replenished by the environment over relatively short periods of time.

The first windmill used for the production of electric power was built in Scotland in July 1887. It was built by Prof James Blyth of Anderson's College, Glasgow. Its height was 10 metres. Wind turbine was installed in the garden of his holiday cottage. It was used to charge accumulators developed by the Frenchman Camille Alphonse Faure, to power the lighting in the cottage. 

Solar-powered photovoltaic (PV) panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business. Light striking a silicon semiconductor causes electrons to flow, creating electricity. Solar power generating systems take advantage of this property to convert sunlight directly into electrical energy. 

Plants trap the solar energy and convert it into chemical energy by the process of photosynthesis.This chemical energy in the form of carbohydrates or sugar is used as food.

Solar energy is the renewable source of energy which is essential for all living beings.All plant life needs solar energy to prepare their food by photosynthesis and the animal life is dependent on plants directly or indirectly.So it is the prime source of energy.

The Sun is the primary source of energy for Earth's climate system is the first of seven Essential Principles of Climate Sciences. Principle 1 sets the stage for understanding Earth's climate system and energy balance. The Sun warms the planet, drives the hydrologic cycle, and makes life on Earth possible.Each second, more than four million tonnes of matter are converted into energy within the Sun's core, producing neutrinos and solar radiation.

The forms of energy from the sun are heat and light.
