Advantages And Disadvantages Of Renewable Sources

2274 Words10 Pages

Energy is one of the reasons why humanity continues their survival. Because of it, households have electricity and cars can be driven. Basically, it is the prime root why people can do "things." It can be extracted from two sources, namely non-renewable sources and, the subject of the case study, renewable sources. Renewable sources include wind, water, sun, geothermal and biomass. It is clean, sustainable and may be considered as infinite. In comparison with non-renewable sources, it does not emit gases hazardous to the environment and in the health of the community. These advantages come with disadvantages. The construction of these sources is expensive and takes a large amount of space. Moreover, the utilization of these may be affected by the altering weather conditions. The aforementioned renewable sources can be found in the world, specifically in the Philippines. Wind turbines, namely Burgos Wind Farm and Bangui Wind Farm, are located in Ilocos Norte. In Negros Occidental, a solar plant was built producing 22 megawatts. According to Department of Energy, in 2011, the Philippines’ installed power capacity is divided with coal being the biggest, 30 percent, secondly, the natural gas at 18 percent and then oil-based plants at 19 percent. On the other hand, renewable sources have these share; 22 percent for hydroelectric plants, 11 percent for geothermal and 0 percent for wind, solar and biomass. The total installed capacity is 16,162 megawatts. The dominance of

    9). Furthermore, Canada consumed 330 million tonnes of fuel in 2016, with a global energy demand of 2.5% (BP, 2017, p. 9). Subsequently, in 2016, 30% was from oil, 27% from natural gas, 27% from hydroelectric, 7% from nuclear, 6% from coal, and 3% from renewables (BP, 2017, p. 9). However, Alberta does not follow the global trend for energy consumption from similar fuels. To illustrate, in 2016, 44% came from natural gas, 39% from coal, 9% from wind power, 6% from hydroelectric, 3% from biomass fuel, and 1% from oil and diesel (Energy Alberta, 2017).

  • Florida's Energy Essay

    1738 Words  | 7 Pages

    In Florida, electric utilities use natural gas as their main source of generating power. In 2015, Florida generated 156 Terawatt hours of electricity from natural gas (PSC). This vastly overwhelms other sources such as coal, at 47 TWh, nuclear, at 28 TWh, renewables, at 3 TWh, or oil, at a meager 592 GWh (PSC). This excessive use of natural gas puts the majority of Florida dependent on a resource that probably will not be around in a hundred years. The capacity of Florida’s renewable sources is rather disappointing.

    When people are not aware of where their energy comes from, it threatens their values and ideals. Aldo Leopold discusses these dangers in his essay, Good Oak, suggesting solutions to prevent them and improve the environment in the process. Energy powers many of the things key to life. As pollution and environmental destruction become a more imminent threat, humans must control their use of energy, preferably making sure not to use more than is necessary to sustain them. People who do not fully control the sources of their energy may take it for granted and waste it, however if they make changes in their lifestyle, these dangers can be avoided.

    In today 's society almost everything that we use in our everyday lives requires some kind of energy source. With our reliance on these sources growing exponentially we have started to become more dependent on other countries to supply our fuel. With this dependence countries debt continues to grow and this has a very negative effect on the country 's economy. Energy can be split into two main groups renewable and nonrenewable. The difference between these two is the fact that one we cannot exhaust and the other we only have a limited supply of.

    wind energy and solar energy are both renewable types of energy they create no pollution and are fully sustainable as they are both powered by natural sources and if there is no wind one day the solar panels can generate energy and if it 's cloudy another day the windmills can generate energy also the energy created during the summer can be sold to the grid for extra capital that can be used for field trips, renovations, etc. Geothermal heating systems are rated the most efficient and eco-friendly heating systems. The system works using buried coils that contain a liquid, typically a mix of water and antifreeze. The liquid is warmed to the same temperature as the earth and then runs through to the home where a compressor extracts the heat but not only that geothermal heating requires no fossil fuels so it is very eco-friendly LED lighting is an efficient and eco friendly lighting alternative because they waste much less energy in converting to light compare to incandescent lights which waste 90% of the energy to convert to heat not only that LED lights last up to 15-25 times longer that traditional light bulbs this makes LED a much better source of lights than others because it wastes less energy and it is more efficient at doing its job this is so much better for the environment because it uses less energy that other lighting sources

    Nowadays, we usually use the newer term called “wind turbine”.1 About four percent of the energy created in the United States comes from wind energy,2 and over 100 countries are now following in this trend and produce energy through the use of wind. This not only shows that a wind energy has great potential in the future, but also how popular it already is. It can be said that the more countries there are that using wind energy the better it is for our world. It is better because wind energy is a sustainable energy source.3 Looking back already at around 1000 AD wind power used and spread around northern Europe, starting with Holland.

  • Non Renewable Resources Essay

    2.1 INTRODUCTION Non-Renewable Resources are resources that have the potential to be used up due to consumption or overuse, they have production, development or replenishment rate that cannot match up with the depletion rate. In short these are resources that can be finished, output exceeds input, and they are infinite. Non-Renewable resources vary from non-renewable fossil fuels like coal, natural gas and oil, non-renewable alternative energy sources like nuclear energy and deep-earth geo-thermal energy, soil, and minerals (Botkin & Keller, 2012). These non-renewable resources range from a few years, up to thousands of years to replenish. The local as well as global challenge, is that most non-renewable resources are directly exploited by humans and their existence is widely threatened were usage

(Sapnu, R., Balabo, D., & Cervantes, D., 2007) "There is a Japan International Cooperation Agency study that says that if we will not conserve water, there may be some problems. But of course we can always start conserving now and look for other sources," Lopez (2013) said. Studies have shown how water conservation and appropriate water utilization are significant as early as today.
