Essay about Solar Power: The Future of Energy

1431 Words6 Pages

I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free…show more content…

If we choose to switch to solar energy in future, it will greatly save our environment because, it does not pollute our air and it is reasonably efficient. It will help reduce global warming, and thus a future green environment with no pollution from fossil fuels, and other conventional sources of energy. To add on that, it will also help in conserving our remaining fossil fuels so that it may not run out in the coming 100-500 years, as it has been predicted. In addition, solar energy operational costs are manageable. It is free from monthly charges compared to conventional sources of energy. Solar energy does not require raw materials such as oil and coal, and once the panels are built, there will be no monthly charges. In addition, the prices of fossil fuels are increasing day by day, and this means conventional energy will be very expensive. Solar energy will remain the most capable world’s future power supply because, it is cost effective once the plants are built, and there will be no transport costs like for conventional energy sources. Therefore, solar energy is cost-effective, and will help in future energy supply, as the maintenance cost is affordable, as long as they are installed properly, and are working efficiently ( Hans, 2012). Furthermore, with the improvement and advancement of technology, it will increase its efficiency, and cost of production thus, making it more cost effective and the world’s best

Alternative Sources of Energy Essay

As the population continues to increase day after day, so does the demand for oil and other natural resources. Eventually we will get to a point where we will need to find different ways of efficiently producing energy at a low cost. Twenty to thirty years ago it was hard to imagine what sources of energy (other than obvious possibilities like solar panels and windmills) that could efficiently supply the world. The advancement of technology today is opening new doors in the energy field that are likely to change the way we think about energy. With so many different sources of energy that are prevalent around the world, the challenge is found in harvesting and securing the energy at its source, and doing so in an efficient…show more content…

Clearly there are many difficulties that would have to be addressed including maintenance, air space issues, safety, etc, but flying wind farms are a potential source of future energy. wind.png Another form of energy that could become very useful and resourceful in the near future is the transformation of human waste into energy. An article by Janet Zimmerman describes a process being developed by an engineering firm named UC Riverside. The new process "uses heat and pressure to turn human waste into clean energy," saving millions of dollars and reducing pollution in the process. This idea has the potential to change the energy industry since there will never be a shortage of human waste. The first step of the process "pumps a combination of municipal sewage, sawdust and water into a pressurized reactor that is heated to almost 1,400 degrees." (Zimmerman). A senior development engineer with UC Riverside, Junior Castillo, explained that the extreme heat transforms the mixture into different gasses like carbon dioxide, methane, and carbon monoxide. In the later stages, these gasses are converted into substitutes for natural gasses. The goal is to eventually use the gas product to heat the reactor to increase efficiency. Although this process is still under development, they plan to have a functioning plant running within the next five
