Introduction
“Green” (or alternative) energy is a substitute energy source for fossil fuels. Alternative energy is interchangeable with Renewable energy since the sources that are generated are natural and cannot be exhausted, all of which have minimal environmental impact. Alternative energy sources include solar power, which is acquired from the sun; wind power; water energy, which produces hydroelectricity; and biomass energy, which comes from plants. Due to these sources being free and causing no harm to the environment, they are increasingly being used around the world. The energy sector has been growing, as governments are adapting environmental policies to reduce pollution and welcoming alternative energy sources.
Alternative energy has many economic, environmental and social benefits. Economically, alternative energy satisfies the continuous and ever-growing demand and cost of energy. As the world populates and new discoveries are made on a daily basis, energy sources are not only being exhausted, they are also harming the environment, and thus people. Due to the high demand for energy and not so high supply, prices are rising day by day. Alternative energies are the solution to this problem, as their cost ranges from nothing to low. Environmentally, switching from fuels to alternative energy saves our world from impacts such as pollution, global warming and deforestation. Socially, our growing dependence on petroleum from around the world can be risky, as supply
Fossil fuels and other power generates are slowly changing the world. Alternative power sources are slowly becoming more popular in everyday life while the technology progresses. Using these power sources that don’t pollute the atmosphere could be the change in the world that completely changes the way the world uses energy. Engineers and technicians have been producing these alternative ways for years and years. A few, but not limited to consist of: Solar panels, Wind turbines, Wave tech and much more.
Renewable energy: energy in which comes from natural resources that are naturally replenished, such as sunlight, wind, rain, tides, and geothermal heat (Bhatia, 2014). This essay is focused on the main three renewable energies, wind, sunlight, and water. Renewable resources are well on the way to out rule the fossil fuel industry because of the diminishing amount of fossil fuels left in the world and increase of renewable resource use, the damage fossil fuels do to the environment, and the various positive aspects that renewable resources bring.
These alternatives can be helpful in reducing carbon emissions while ensuring the energy independence . These sources are wind ,solar ,geothermal, hydro, nuclear and renewable bio fuels. Some of these sources are renewable , meaning they can be replenished, while others like nuclear, are non-renewable, yet are clean sources of energy. For better sustainability , society continues to explore the challenges of these energy options to help implement the necessary changes for an environmentally friendly and energy independent future.
These sources of energy have a great upside, but right now are incredibly inefficient compared with fossil fuels because of the lack of funding and worldly push (2009). If there isn’t a bigger investment in these alternative energies, fossil fuels are going to maintain their stranglehold on all the economies of the world (Lomborg, 2009).
Generating and supplying more green energy in the US can have a big impact in the environment and in our economy. With more green energy resources a big amount disasters that affect our environment can be reduced. Such disasters include oil spills, nuclear leaks and the emission of harmful pollutants. Electric power plants are one of the biggest contributors to pollution in the country due to the amount of carbon and sulfur dioxides that are released into the air. Carbon dioxide emitted into the air is confirmed to contribute to global warming and sulfur dioxide causes acid rain, which can kill plants and animals in lakes and rivers. In comparison, green energy is generated in much more natural and harmless methods that don’t affect our environment. Renewable energy wind, solar, geothermal, hydroelectric, and biomass provides substantial benefits for our climate, and our health.
In the United States today we face growing costs in providing homes and businesses with electricity with the current costs and demands of fossil fuels. Fossil fuels are becoming less common and more expensive with each passing day. An alternate source of energy must be found to combat this growing dilemma, a source that is already providing 13% of our countries energy. Hydro, Solar and Wind energy all three of these being able to provide a potentially infinite amount of energy, so why have we not committed to taking advantage of these sources of energy? Alternate fuel sources for electricity such as Solar energy, Hydro energy and Wind Turbine should be more commonly used for each area in the United States to reduce our reliance on fossil fuels.
In the past hundred years we have been relying on fossil fuel as the major sources of energy, until now people are starting to see what harms fossil fuel does to our environment, and people are staring to see that we are running out of this sources, but likely with the advancement of technology scientist have been able to find something that will replace fossil fuel, and help clean our environment. This replacement are Alternative energy sources. These sources can be described as energy that will be less harmful to the environment as well as humans, cheap, and comes from sources that we won't run out of. One of the most popular source of alternative energy is solar energy. Solar power is the energy
Alternative energies, “energy sources which are not based on the burning of fossil fuels or the splitting of atoms,” (qtd. in “What Are Alternative”) are a controversial issue in the United States today. Because of their cost and existence that goes against normal American energy standards, efficient forms of alternative energy generation, like solar, wind, hydroelectric, and geothermal energy generation have faced a bit of a social stigma in the past, where people associate those who use alternative energies to be either hippies or hipsters. Because of their general unpopularity, alternative energies have seen little use in America, with the country heavily relying on more
In the environment there are many concerns on how to make this a better place to live. One of the biggest issues is our energy and power sources. Green energy is a term used for sources of power and energy that are environmentally friendly. Basically this includes anything that is renewable energy. Renewable energy is considered energy that is constantly being replaced such as wood, vegetable matter, and trash. Green energy 's main focus is to use sources that can cut down on pollution. Some of these sources of power and energy are Biomass energy, geothermal energy, hydropower, nuclear energy, solar energy, wind energy and tidal energy. People hope that these will help use more natural sources to produce energy. In several countries you
There has been much controversy in recent years with regard to the human dependence on oil and benefits associated with alternative energy sources. Society has generally accepted the fact that most energy sources used in the present are undesirable because of the impact they have on the environment, because they are limited, and because they have a negative effect on society as a whole. Technology has brought on a series of alternative means of generating energy and emphasized the fact that humanity actually has a choice about the energy sources that it uses, thus providing people with the opportunity to get actively involved in assisting both themselves and society as a whole.
Alternative energy is a term that refers to many different types of energy. These energies include hydrogen energy, bioenergy, geothermal energy, wind energy, solar energy, water energy, and nuclear energy (31). They are all different energies and produced in different ways. They all have one thing in common though; they all produce energy without using fossil fuels. (Schlager and Weisblatt, 33, volume 1)
Renewable resources are also known as alternative energy sources. Alternative Energy is any source of energy that can be renewed (Issit). Renewable Energies include hydrogen fuel, biomass fuel, hydropower, solar power, geothermic energy, and nuclear power. Hydrogen fuel is an amalgamation of hydrogen and oxygen which is used to produce electricity (Issit). Biomass fuel is made from materials which have already been used, such as compost, and can be used to generate electricity (Issit). Hydropower can be created through moving water or wind to generate electricity (Issit). Using sunlight to produce electricity is called solar power (Issit). Geothermic energy is energy made by the heat under the earth’s mantle (Issit). Nuclear power is
For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
This report presents an alternative energy is any energy source that from fossil fuel. We need to turn to alternative energy in general. Firstly, we were in danger of ruining the planet’s climate through fossil fuel emissions. Furthermore, we cannot keep using fossil fuels forever that will run out someday [1]. In addition, the problem of the current energy that we can focus was energy security and independence viewpoint because our nation has increased its dependence on foreign oil supplies instead of decreasing it especially from nations under the rule of a dictator or unstable countries where human rights violations are common [2].
