Renewable energy are considered to be important in improving the security of energy supplies by decreasing the dependence on fossil fuels and in reducing the emissions of greenhouse gases. The viability of isolated systems using renewable energy depends largely on regulations and stimulation measures. Renewable energy are the natural energy re that are inexhaustible, for example, wind, solar, geothermal, biomass, and small hydro generation. Among the renewable energy , small hydro and wind energy have the ability to complement each other. In a location with enough average wind speed and a suitable area for wind turbines, wind pumped storage system is a good combination with a hydro power plant.
Using wind energy would be the best way to solve the world’s pollution problem that cause by burning of fossil fuel. The reason why I personally think that is the best way to solve the pollution is because the wind energy (wind turbine) only uses wind to produce electricity. Wind energy is plentiful, renewable, clean and produce no harmful gas. The effects to the environment are less problematic than the other nonrenewable energy source. It is also cheaper than coal or burning gas.
There are many types of technologies to do this, for example parabolic trough, compact linear Fresnel reflectors, Stirling solar dish and solar power tower. Floatovoltaics are simply photovoltaics that float on the surface of water, for example in canals, lakes, water reservoirs and ponds. This allows for the photovoltaics to collect energy while not taking valuable land, reducing water evaporation and working more efficiently because the photovoltaics are being cooled down by the
After the evaporation, the remaining part must be warmed up and condensed, so it can become freshwater (Nield, 2015, p.1). B. Advantages Using pervaporation will help us in many different ways. According to Danise (2015, p.1), the membrane can be built using cheap materials, which would be a great choice for developed countries. The technology can also clean water from high concentrated salt effectively (Nield, 2015, p.2).
Therefore not all countries in this world will be able to afford or product desalination plants. Another disadvantage are the environmental impacts the desalination plants make. Removing the salt removed from the water is a big issue. The discharge which is also known as brine, lowers the amount of oxygen in the water at the disposal site, which leads to the killing of animals that are not used to the higher levels of salt. In addition, the desalination process uses numerous chemicals including chlorine, carbon dioxide,
Take an example from the world banks in the 1950s and '60s, huge hydropower projects. Making dam cast huge but produce less energy than expected. Their biggest beneficiaries are mining companies and aluminum smelters, while Africa's poor inequality increase. This means the world bank got benefit by mining but the people who want or need help couldn’t get much support from this project. Only the debt increased.
Health Over Wealth In this world where most nations have some type of conflicting alliances, it is hard to find resources and obtain them relatively cheap. Most people do not concern themselves with specific issues if they do not directly impact their lives. As a result, a large portion of people do not understand fracking. Merriam-Webster defines fracking as “the injection of fluid into shale beds at high pressure in order to free up petroleum resources (such as oil or natural gas).” Fracking impacts our environment in several different ways: it creates man-induced disasters, it ruins water supplies, and it even causes serious health issues. Fracking harms our environment, yet people offer certain arguments for the continuation of fracking.
In only a few decades the water level has dropped drastically. I don’t think a pipeline should be built because it don 't think it justifies shifting resources of one community to help the other. The problem will still exist and the pipeline is a very expensive limited time solution. There are other ways to try to fix the problem rather throwing so much money around. Regarding the farmers rights vs the fisherman 's rights, its a matter of what is more important right now.
In addition to the huge amount of energy available, it is the kinetic properties of water waves that allows it to be highly efficient for cultivation. Since ocean particles directly stimulate energy capturing mechanisms, the mechanical and direct systems makes ocean power cultivation highly efficient. Even in one of the early creations of collecting ocean wave power in the 1970s, people have managed to capture 90% of ocean wave energy, where 84% of the energy could be successfully produced into electrical energy.
Agriculture immensely adds to the nutrient and chemical pollution due to the fertilizers used on crops. When rains or winds come through the fertilizer is carried from the fields into the rivers and streams that then lead into the ocean(Effect of Runoff). Red tide had been a huge issue that is unpreventable and caused by dinoflagellates (Red Tide). Red Tide is a type of algal bloom that takes up oxygen in the water. When the oxygen levels in the ocean are lowered it can kill many plants which is very unfortunate for the manatees considering they are herbivores and with their food supply being depleted they may suffer from starvation.
