Production of hydroelectricity is not harmful to the surroundings. It is safe, powerful and does not produce any waste.
Besides, it is very easy to produce and that makes it the best energy alternative when the electricity demand is high. Water in a reservoir can be released when required, hence the generation of energy is simple.
The possibility to control hydroelectric power makes it the solution to less controllable sources of energy. It can be used to power factories, homes, schools, offices, and hospitals. Furthermore, it is one of the fastest ways employed by developing countries to take affordable electricity in the rural areas.
Another great advantage that makes hydroelectric power a good energy option is that it will never run out provided there is a reliable supply of water. The moment the dam is built, the cost of electricity reduces, no pollution, no waste and the electricity can be generated when required.
2. Nuclear Energy
Nuclear energy is mainly used to generate electric energy. Nuclear power plants are in charge of producing electricity. The nuclear reactors found in the nuclear power plants generate nuclear fission reactors.
These reactions result in the production of thermal energy which is converted to mechanical energy then to electrical energy.
Nuclear energy generate electric power that is used in homes, businesses, hospitals and schools. It produces energy that is clean, renewable, does not pollute the air or generate greenhouse gases. The nuclear power plants can be built both in rural or urban areas as they do not affect their surroundings.
You can also recycle the generators and the steam powering the turbines. Steam turns into water after it is cooled in a different structure referred as a cooling tower and reused to generate electricity. The extra steam is easily recycled into the air, where it poses no risk as it is simply fresh water vapor.
3. Wind Energy
Wind energy (wind power) is the process used to generate electricity from the wind. Wind energy is a great energy alternative since it is clean, renewable, free, cost-effective, non-polluting and using it has no effect on its next supply.
Wind energy is quite affordable. A single wind turbine is enough to produce energy for the entire household. Since wind energy does not pollute the air the wind turbines create electricity without producing poisonous waste, radioactive and without the use of fossil fuels.
Wind turbines can turn the wind power into mechanical power which can be used in different activities such as pumping water. In addition, the turbines can make use of generators in converting wind power into electricity.
Wind energy is mostly used in the farms. The wind electric power is transmitted to the users via transmission systems that include towers, substations, and electric transmission lines.
The biggest challenge of using wind electricity is that it comes and goes and cannot be stored to be used in future. Wind energy requires integration with sources of energy as it is not reliable.
4. Solar Energy
Solar energy is undeniably the most reliable and cleanest type of renewable energy you can find today. It can be used in different forms to aid in powering your business or home.
Use of solar energy to power electronics is quite popular nowadays. Solar-powered chargers can charge almost every gadget: tablet, cell phone or e-reader. What’s more, you can even charge flashlights that are solar-powered by merely exposing them to sunlight.
Below is a list of solar devices:
– Cell phones
– Solar dryers
– Solar air conditioners
– Solar-powered flashlights –rechargeable
– Solar visor radios
As people do away with fossil fuels and look for renewable energy sources for daily electronics, it is certain that solar energy will be employed by many for all products that can charge with the use of sunlight.
5. Geothermal Energy
Geothermal energy is trapped from the heat on the ground. This kind of energy is from the radioactive decaying matter.
Geothermal energy can be used as an alternative energy in the following ways:
1. Industrial processes- The geothermal power can be used in drying timber, digesting paper and wood pulp.
2. Power production- Geothermal is a promising source of energy that has been employed successfully in areas that depend entirely on imported fossil fuels such as oil and coal.
3. Horticulture- Geothermal waters are used in several areas to heat up small-scale greenhouses for the growth of flowers, fruits, and vegetables.
4. Geothermal prawn farming- The emergence of geothermally heated prawn farms is on the rise. The farm uses heat exchangers –that utilizes heat from the waste water of the power station- to heat up its water.
5. District and space heating- District setups distribute hydrothermal water that is found in geothermal wells to buildings and houses through a chain of pipes. The geothermal heating systems can save the cost of heating natural gas by 30%-50%.
6. Biofuel Energy
Biofuel also referred as Agrofuel. It is derived from bio waste or biomass. Biofuel can be used for several purposes; however, the chief purpose is transportation. Many vehicles need fuels, which can offer high power and density so that storage can be simpler.
Biofuels are essential in the transportation sector since they are rather energy dense compared to batteries and electricity. They are also quick to dispense through the present infrastructure with just small changes contrast to hydrogen.
Besides biofuels are somewhat comparable to petroleum-based fuels, thus only minor changes are needed for biofuels to work smoothly in vehicles.
The main use of biofuel is on the motor vehicle industry as this sector is the biggest consumer of standard fuel. The biggest challenge with the motor vehicle sector is that it is extremely huge hence meeting the demands with the present biofuel technology is close to impossible.
Hydrogen is conceived to be a secondary source of energy, usually known as an energy carrier. The purpose of energy carriers is to shift, store and ship energy in a form that can be used with ease. Electricity is a popular form of an energy carrier.
Hydrogen as a vital energy carrier in the days to come has several benefits. For instance, a significant amount of hydrogen can be simply stored in several ways.
Hydrogen is believed to be a highly effective and non-polluting fuel that can be employed in heating, transportation and power production in areas where it is hard to use electric power. In some cases, it’s cheaper to transport hydrogen by pipelines instead of sending electric power to faraway places by wire.
Presently hydrogen is mostly utilized as a fuel in the NASA space plan. You can use liquid hydrogen to impel space shuttles and any other rocket, whereas hydrogen fuel cells control the shuttle’s electrical systems. In addition the hydrogen fuel cell can generate clean water for the shuttle squad.
