Secondly evaluate the sustainable development of biofuel and wind energies. Finally conclude arguments on potential renewable energy to replace fossil fuels. Owing to the increase in the global population accompanied by an increase in energy demand as a result oil price crisis. Many governments... ... middle of paper ... ...f renewable energy or carbon-free debate and argument. This essay has attempted to evaluate the potential renewable energy both in terms of sustainable development and reducible global warming.
Common types of fossil fuels are coal, oil and natural gases. An energy source that conserves the environment and is healthy to people is the top concern. People today are too dependable upon destructive fossil fuels for energy, which is why our attention should turn to renewable energy to conserve our natural resources. Furnishes of fossil fuels will eventually disappear and then we will loose our main source of energy for things that we do everyday. This is why the importance of finding other sources of energy is so significant.
He wanted to reduce the pollution rate across America. The main way Obama wanted to acquire less pollution was through the use of renewable resources. We have a variety of active renewable energy sources across the country, however, it is not enough to be significantly beneficial (Hudgins). In America, the most popularly used renewable energy sources are wind and biomass. Wind power is costly at first, but it is cheap to operate.
If the sun isn’t shining, wind isn’t blowing or if there’s no water flowing we can’t rely on these resources unlike fossil fuels which we can store up. Using fossil fuels is actually cheaper than using renewable resources. It cost more to generate electricity from the resources and no one wants to pay more for their monthly utility bill. The final reason would be that most of renewable resources require constant movement, kinetic energy, or to be constantly be present. If one day they are not present we won’t have
Biofuels are not only used in foods, but can be used in many other ways such as transportation. According to research, energy that is created by biomass is less expensive than using coal/oil. Biofuels work just as much as fossil fuels but use about ⅓ less than fossil fuels do (Biomass Energy). Biofuels are commonly mistaken as an unhealthy gateway, but it is inexpensive compared to using coal and oil. Biofuels also use a high number of pipes stretching across states and even countries, but with biofuels the need for these pipes won't exist.
As has been noted, renewable energy resources can seriously impact society as a whole and provide for a safer and cleaner environment. Although renewable energy resources are usually more expensive than non-renewable energy resources, their benefits on the world outweigh any cost difference or accessibility concerns. Fossil fuels play an active role in polluting lands and the air that humans breathe, and for that reason they should be eliminated and replaced by renewable energy resources in the near future. Slowly but steadily the non-renewable resources that humans use everyday are disappearing, but they can put a stop to it by using renewable energy resources such as solar energy, wind energy, and hydropower energy. Renewable energy is the future of the world.
Why is renewable energy desirable? Since this current unit deals with sustainability of energy, it would mean that the energies that would be sustainable are renewable energies. Currently, most of our energy sources come from non-renewable sources, 87% to be exact, such as Oil, Natural Gas and Coal. All of these energy sources, primarily fuel our societies but in the long run these sources will start to diminish, crippling nations, as they are one of the basics needed to run our societies. That’s why governments are looking for alternatives ways to function the population, so when the current sources run out there will be no dilemma.
Why do we need to rely on renewable sources? Most of the energy that we use today come from fossil fuels such as natural gas, coal, and oil. All of these resources are non-renewable, it can finish one day. In order to have a better world and a healthy environment for the future, people are trying to obtain energy from natural resources instead of non-renewable sources. In the lecture “Renewable energy resources” (2014), Mistry focuses on some advantages and disadvantages of renewable energy.
Greenhouse gases are produced on a large scale by combustion of fossil fuels. A major contributor to greenhouse emissions is the combustion of coal, oil, and gas in power plants. Many options to fossil fuels as a source of energy have been suggested, but with increasing energy demands our society is reluctant to risk a change. Alternatives such as wind energy, nuclear power, and fuel cells have all been suggested, but all have draw backs and limitations. The focus of this paper is expanding fuel cell production of clean energy.
Electricity is a necessity in this day and age. It powers pretty much everything from lights to entertainment devices to workstations and even some of our vehicles. The majority of the electricity we use is generated from coal, oil, and natural gas. A full 83% of electricity generated is produced from these hydrocarbons in North America (Hughes, 2010). With hydrocarbons being a non-renewable energy source, creating a more robust energy generation grid will ease the effect of rising oil, gas, and coal prices when their supply starts to run low.
