INTRODUCTION
It is hard to live without Energy, but it is impossible to find another planet to live in. Energy is everything. It comes in many forms such as heat, electricity, light, mechanical energy. Conventional energy sources such as coal and oil are the main contributors to the global warming. Furthermore, these fossil fuels are not renewable, which means one day we will run out of them. The good news is alternative sources of energy can replace the current technologies we are using. These renewable energy sources are environment friendly as they emit less carbon dioxide, compared to fossil fuels. There are many alternative sources of energies that harness natural forces and resources such as solar power, wind power, and geothermal energy.

TYPES OF RENEWABLE ENERGY:

Solar Energy
Wind energy
Tidal Energy
Geothermal Energy
Ocean Thermal Energy
Bio Mass Energy
Hydel Power Energy

SOLAR ENERGY:
  From environmental prospective solar power is the best alternative source of energy. It is the light and the heat from the sun which is harnessed to generate power. It is created by converting the sun rays into electricity using solar panels. Additionally, solar panels change the sun light that hit it into heat, which is used to heat homes, water, swimming pools, and for cooking

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Commercial concentrated solar power plants were first developed in the 1980s. REAL TIME EXAMPLES:

The 354 MW SEGS CSP installation is the largest solar power plant in the world, located in the Mojave Desert of California. Other large CSP plants include the Solnova Solar Power Station (150 MW), the Andasol solar power station (150 MW), and Extresol Solar Power Station (100 MW), all in Spain. The 370 MW Ivanpah Solar Power Facilities, located in California's Mojave Desert, is the world’s largest solar thermal power plant project currently under construction. WIND ENERGY:

Wind power is one of the oldest forms of energy that benefited mankind so greatly. It is the use of the wind power to produce electricity. In the past, people used it to navigate water, to pump water and to dry clothes. Today, we use it to produce electricity. In this technology, when the wind blows, it rotates the blades of the wind turbines. This rotation runs electric generators. REAL TIME EXAMPLES:

USA
India
China
UK
Italy
France
GEOTHERMAL ENERGY:
Geothermal energy is one of the main sources of alternative energy. It is the heat of the earth, which is continuously produced in the core of the earth. It is very beneficial to the earth and it atmosphere as it doesn't produce any pollution. In this technology, Wells are drilled to pump heated water and steam. Then, that steam and heated water are purified to drive wind turbines which produce electricity. It works best in sunny climate regions.

REAL TIME EXAMPLES:
USA, Philippines, Mexico, Ice land, Japan, Kenya, Russia, turkey, Portugal, Germany etc are the countries which has the geothermal energy installed in it. OCEAN THERMAL ENERGY:
Ocean thermal energy conversion (OTEC) uses the temperature difference between cooler deep and warmer shallow or surface ocean waters to run a heat engine and produce useful work, usually in the form of electricity. OTEC is a base...
