The industrial revolution brought great development and wealth to the world, especially the Western Europe. The industrial revolution which cane as a result of the mass production of energy to power mechanical engines gave rise to a feverish pursuit of wealth which resulted in the indiscriminate burning of fossils, coal and other dirty energy sources to fuel industries. This has not come without consequences; the earth today is threatened by global warming which is a direct result of the excessive burning of fossil fuel for centuries.
As global warming and other environmental consequences of dirty energy uses threaten civilization, emphasis is now place on the use of clean renewable energies. The House is lists out some of these renewable energy sources.
- Solar Energy.
Photovoltaic (PV) Solar Energy is taking advantage of the sun’s energy to produce power. Solar power is the fastest growing energy sources today and ranked as the future of clean, cheap and renewable energy source. New innovative technologies are developing at a rapid pace. Solar cells are becoming cheaper, efficient, transportable and even flexible, allowing easy installation.
- Biomass in general terms refers to living and recently dead biological material that can be used as fuel or for industrial production. This source of renewable energy has recently gained considerable attention. In this context, biomass refers to plant material grown to generate electricity or produce, e.g., garbage such as trees and dead branches, sawmill cuttings and biofuel wood chips, and include plant or animal materials used for the production of fibers, products Chemicals or heat. Biomass can also include biodegradable wastes that can be burned as fuel. Industrial biomass is usually grown from various types of plants, including miscanthus, switchgrass, hemp, sugarcane, maize, poplar, a variety of tree species, ranging from eucalyptus to the oil palm, willow, and sorghum. The particular plant used is usually not important for the final products, but it affects the processing of the raw material. Biomass production is a growing industry as interest in sustainable fuel sources is growing.
- Geothermal Energy
This is a very powerful and efficient energy. It is a way to extract renewable energy from the earth through natural processes. This could be done easily on a small scale to provide heat for a residential unit through a geothermal heat pump. It could be done on a large scale through a geothermal power plant for the production of energy. It has been in used to heat bath in Italy since ancient Roman times. It is now best known for generating electricity. Geothermal energy is cost-effective, reliable and environmentally friendly, but could be geographically limited to areas close to the boundaries of the tectonic plate. However, recent technological advances has expanded the range and size of viable resources dramatically, especially for direct applications such as domestic heating
- Wind Energy.
Wind energy is the one of the earliest power source used to move ships with the help of sail in ancient times. Wind power is growing rapidly, and has doubled in recent years. It is the conversion of wind energy by wind turbines into a useful form, such as mechanical energy or electricity. Typically, large-scale wind farms are connected to the local power transmission grid with small turbines used to supply electricity to isolated areas. Residential units are entering production and can power large appliances to whole houses depending on size.
- Nuclear Power
Nuclear energy is obtained from the nuclear reaction. It is a technology designed to extract usable energy from the atomic nuclei through controlled nuclear reactions technology. The only method still in use today is through nuclear fission, although other methods could one day include nuclear fusion and radioactive decay.
The United States, France, and Japan generate a substantial part of their energy from this.
