Most infrastructures are based on the current climate. The cost of rebuilding infrastructure, saving animals and humans that are being affected by climate change will have huge costs. As the climate change, the agriculture will change as well. The crops might not be able to adapt to the changing climate. Diseases might spread. (Holli Riebeek 2010)
c) Solutions to address the negative outcomes of Global Warming
The most considerable way to address the negative outcomes associated with global warming is to reduce the emissions of greenhouse gases being released into the atmosphere. I will focus on the solution of using wind turbines as alternative source to generate energy to reduce the amount of greenhouse gasses.
Scientist has researched different ways to utilize the resources we have on earth. Windmills generate electricity which is an alternative to burning of fossil fuels to get energy. Windmills are driven by blades on a rotating shaft which receives kinetic energy from the wind.
Wind is mass in movement. Mass in movement generates energy. The turbines generate electricity without emitting any greenhouse gases at all. This energy is in addition renewable. This might address the negative outcomes associated with global warming in the way that it doesn’t give off any greenhouse gases (which is the main cause of global warming.) If we use renewable energy sources like wind instead of burning of fossil fuel, we can reduce the greenhouse gases that are causing global warming. (Christoffer Longva, Fornybare og ikkke fornybare energikilder, 2007)
Aspect 2 (Effectiveness of Science)
d) Positive and negative impacts of the solution
To use windmills as an alternative way to generate electricity is a solution that had both negative and positive impacts. The solution is very effec tive because the resource is renewable and it doesn’t emit any greenhouse gases which causes global warming.
Advantages of my scientific solution
Windmills are friendly to the surrounding environment and does not cause pollution. This is caused by the fact that the wind energy is renewable and does not release any greenhouse gases. Therefore, it does not pollute either.
Wind turbines and windmills do not take up a lot of space. Compared to most other power machines, it only occupies two square meters for the base. This means that there are space for many windmills and/or the landmark around the windmills can be used for other purposed such as agriculture. The windmills may also be placed out in the sea.
This way of generating electricity is a way of ensuring the supply of electricity to be steady. This is especially an advantage for LEDC’s, as the wind is free. Wind is available everywhere and it is a free powerhouse. These factors are financial advantages.
Disadvantages of my scientific solution
The most significant disadvantage of wind energy is the fact that the wind is not reliable. If it is storm or little wind, this way of generating electricity won’t work. The wind must be in a speed of at least 4.5 m/s in order for the windmill to be able to generate the energy to electricity. The windmills will not produce the same amount of electricity every time and the supply of electricity will vary.
To make an impact, many windmills are required. Windmills create less electricity than other power stations and in areas where there are many windmills, the noise level is high. People living in the areas of windmills, appears to think that they are unsightly. They feel that the countryside looks unpleasant as windmills are a part of it. Windmills located in the sea may affect the ecosystem and cause imbalance in the ocean.
On the one side, windmills are very beneficial because they are causing no pollution, they don’t take up much space and they ensure a quite steady supply of electricity.
On the other side, the windmills are not reliable because the weather conditions change. They don’t produce the same amount of electricity, they are expensive, they create less electricity than other power stations, and they’re noisy and ugly. (Clean Energy Ideas, 2010)
Aspect 3 (Science and Society)
e) Environmental and Economic factor
(i) Environmental
Living organisms and the environment are being apparent affected by this solution. As the greenhouse gas emission is reducing, global warming is also being subdued. This affects the climate and living environments is many ways. Since global warming has a negative effect on most people, the damage on earth will be reduced. This way of generating electricity is much more environmental friendly and the environment will be improved as global warming is being subdued.
On the other side, the windmills are very noisy and unsightly. They create a high sound level which is causing the areas where windmills are located be unpleasant for people to live. The countryside as a part of the environment is being affected in the way that it is not an attractive place to live.
(ii) Economic
The windmills are expensive and cheap in different ways. The building of the windmills is very expensive. Each windmill has an average cost of between $1.2 million and $2.6 million. (Great Plain Windustry Project 2011) The windmills require the wind to be reliable. The wind can not be too weak or strong. The supply of electricity is unsteady. They are therefore very expensive if they don’t give you the electricity supply you expect.
The wind energy is free the resource is to find everywhere in the world. To generate wind to electricity is free. As long as the weather conditions are steady, you are ensured to be generating electricity. This powerhouse is to find everywhere and is a clever way to generate electricity.
f) Personal opinion
I personally think that the overall limitations outweigh the potential benefits. Windmills are a clever way to generate electricity, but you need to have steady weather conditions in order for the electricity supply to be steady. Other power stations such as the ones burning fossil fuels are more effective. This powerhouse is in contrast worse for the environment and will continue causing global warming.
