RENEWABLE ENERGY

A renewable energy source means energy that is sustainable – something that can’t run out, or is endless, like the sun. When you hear the term ‘alternative energy’ it’s usually referring to renewable energy sources too. 

The most popular renewable energy sources currently are:

  1. Solar energy
  2. Wind energy
  3. Hydro energy
  4. Tidal energy
  5. Geothermal energy
  6. Biomass energy 

Solar power is energy from the sun that is converted into thermal or electrical energy. Solar energy is the cleanest and most abundant renewable energy source available

Wind power or wind energy is the use of wind to provide mechanical power through wind turbines to turn electric generators and traditionally to do other work, like milling or pumping.

Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall

Biomass Energy  is a modern name for the ancient technology of burning plant or animal material for energy production (electricity or heat), or in various industrial processes as raw substance for a range of products. 

Geothermal energy is heat within the earth. The word geothermal comes from the Greek words geo (earth) and therme (heat). Geothermal energy is a renewable energy source because heat is continuously produced inside the earth. People use geothermal heat for bathing, to heat buildings, and to generate electricity.

Ocean Energy: Ocean energy refers to all forms of renewable energy derived from the sea. There are three main types of ocean technology: wave, tidal and ocean thermal. 

Renewable power is increasingly cheaper than any new electricity capacity based on fossil fuels, a new report by the International Renewable Energy Agency (IRENA) published today finds. Renewable Power Generation Costs in 2019 shows that more than half of the renewable capacity added in 2019 achieved lower power costs than the cheapest new coal plants. 

 What advantages do we find in renewable energy against fossil fuels? For thousands of centuries we have used fossil fuels such as coal, oil and natural gas in the day to day of the humanity. But these resources are limited, and with them we pollute the environment. Are then renewable energies a viable alternative to their use? From Bester we believe and are convinced that so it is.

Demand for energy and associated services, to meet social and economic development and improve human welfare and health, is increasing. All societies require energy services to meet basic human needs (e.g., lighting, cooking, space comfort, mobility and communication) and to serve productive processes. Since approximately 1850, global use of fossil fuels (coal, oil and gas) has increased to dominate energy supply, leading to a rapid growth in carbon dioxide (CO2) emissions.
