Physics expert suggests Namibia develop alternative sources of storing renewable energy
The Anthem of the Energy Crisis
The world has been in any energy crisis for generations now, at least. Mankind has used and used and depleted the Earth’s non-renewable energy resources and it has now become difficult to provide humanity with the energy that it demands. Consequently, work on alternative sources of energy has been made which includes the work on renewable energy like solar for almost 4 decades now. This article discusses how solar energy is the cleanest source and the fluctuation in its pricing recently.
Renewable Energy World
Energy conservation is a topic that is close to almost everyone’s hearts today. We are just beginning to realize how fast we will run out of non-renewable sources of energy like coal and water. As a consequence, alternate forms of energy are constantly being experimented with and tested on in order to provide mankind with energy for the coming generations. While this debate was opened many, many years ago, we also decided to consider renewable sources of energy like wind and sun energy. These forms of energy were expensive back in the 70s, but over the following years, seeing the energy crisis that the world is going into, these alternate forms of energies have gone down in terms of pricing. Statistics tell us that the pricing of solar energy has gone down from $150/Watt in the 1970s to 60 cents/watt today. That is a huge drop which allows us to envision using solar panels and actually making a difference in the world.
Advantages Of Renewable Energy
If you live in a part of the world that sees sunny days almost 80 to 90 percent of the 365 days of a year, then using solar energy can save us big costs and also help us conserve energy. Sustainable energy solutions are being worked on every day now and their utility is completely relevant to the lifestyles of most people. Furthermore, the project of solar energy increased employment in the U.S. in the recession of 2007. Companies hired new people to install panels and some trained older employees to install them and work with them. An advantage of solar energy is that it is installed right where it is needed. This means that it eliminates the need for electrons to travel for miles an hour, losing 6 percent of their total efficiency in the travel process. This was also better because it was providing more energy than the other sources. The best about solar energy is that it is absolutely clean to use and that anyone can maintain and fix it for themselves, even though there are many solar light suppliers present.
Solar energy systems home may still be expensive to buy and install but what many companies have come up with is more of an installment plan where you make one big payment and keep on paying small amounts every month. The world needs solutions for the energy crisis and solar power and wind power seems to be the solution we are looking for. Houses and offices can easily be powered by solar energy and because there is hardly any wastage, this form of energy is also more efficient compared to hydrothermal or hydroelectric. With such astonishing statistics, the number of solar light suppliers has increased in the recent years and these firms are also working on sustainable solutions for humanity. While there is a competition in alternative energy, including wind energy, biomass and geothermal and they are being effectively used to solve the energy crisis, solar energy remains unparalleled and demands to be invested in and it is important to learn how do we use solar energy.
Energy is the power that lights up our homes, helps us in transportation and helps manufacture every kind of products. Creation or destruction of energy is not possible and it can only be changed from one form to another. Types of energy include both renewable and non-renewable resources.
Non-renewable Sources of Energy
Coal, petroleum and natural gas are fossil fuels that we use for producing various forms of energy. These are non-renewable sources of energy as they cannot be regenerated or created again. Uranium is also a non-renewable energy resource, which is employed in nuclear power plants.
To produce energy, these fuels undergo a process called combustion. Combustion leads to pollution, as it releases sulphur dioxide and carbon monoxide that lead to global warming and acid rains.
Those sources of energy that can be reused over and again include wind, solar power, biomass, hydropower (water) and geothermal power. These are referred to as renewable or alternative energy, and can be defined as a form of energy that does not expend earth’s limited resources and can be refilled quickly and easily.
Renewable energy does not generate pollution in gathering and production of power, unlike non-renewable energy. The sources of renewable energy are:
ØWind turbines that generate or create electricity from the wind. ØSun is the biggest source of energy and produces solar power. Direct and indirect energy from the sun can be used to create electricity using solar or photovoltaic panels. Such panels are used in office and homes to generate electricity.ØNatural products like wood, corn and manure help create biomass, which are used to generate heat by burning them.ØHydropower comes from rivers and dams. A turbine is located at places with high water currents. Flowing water activates the turbine, which in turn generates electricity. ØThe earth’s crust generates geothermal mass through the extremely hot water or stream that is extracted from the crust by engineers. This is used to generate electricity.
Sun is the biggest source of energy that produces other sources. For example, wind is produced through the interaction between the atmosphere and the solar energy. Not only does the wind drive wind mills and power sailing ships, but it also helps a great deal in producing electricity.
Similarly, when solar energy interacts with the oceans, it sets hydrological cycle in motion. This cycle leads to rainfall and creates other potential energy through flow of water in rivers and streams, which in turn help create hydroelectric power.
Renewable energy has many advantages. It can be replenished and facilities generating this energy do not require large maintenance costs. As this form of energy does not produce harmful products and gases such as carbon monoxide, it does not harm the environment either. The fact is that the earth receives 6000 times of energy that is used throughout the world. The need of the hour is to transform this energy to suit our requirements and to help create and sustain a better environment for the current and future generations.
