The Effects Of Renewable Energy On The Earth 's Climate

Energy is an important part of life producing the power of movement, heat, and production of electricity in many different ways. Therefore, choosing the correct source of energy is important for the environment and humans. Renewable energy that produces electricity never runs out, causing a lower environmental impact. Solar, Biomass, Wind, Geothermal, and Hydropower energy should be used globally to produce electricity. On the other hand, producing electricity from nonrenewable energy sources can be very harmful to humans and the environment. Humans can easily be dependent on it, which may not be the best option when it comes to finance, efficiency, sustainability and more. Approximately 52% of the US electricity comes from polluting sources like natural gas, oil, nuclear, and hydropower that have a lot of disadvantages effecting the environment in a negative way.

The United States is the second largest producer of greenhouse gases in the world, and yet is doing very little to fix this startling statistic (Dennis). The US’ reliance upon outdated energy sources continues to harm both the environment and the economy by producing millions of tonnes of pollution every year and costing the government billions of dollars (“Fact Sheet: Clean Power Plan”). Fossil fuels have been the main energy sources in America since the industrial revolution, and it is time to make a change. Renewable energy is energy harnessed from sources like the sun, wind, or water, and has little to no negative effects on the environment (“Renewable Energy Technology Basics”). The United States needs to integrate and increase the use of these types of energy across the country, as well as implement positive environmental policies, to prevent further pollution of the earth and combat the effects of climate change.

Global warming and climate change is one of the most pressing issues in the contemporary society given its continued impacts on human life and the world’s ecosystem. The considerable effects of this issue have raised huge concerns among policymakers, governments, and the public. As a result, various initiatives have been developed in attempts to lessen global warming or climate change, especially those related to reducing the emission of greenhouse gases to the Earth’s atmosphere. Governments across the globe including the United Kingdom government have adopted various policies that focus on dealing with the issue. There are various policies that help in dealing with the issue including lessening greenhouse gases emissions, adapting to the effects of climate change, and geo-engineering of the climate system. The attempts by the UK government to address this problem require an understanding of the increasing energy demands and its future impact and use of suitable renewable energy sources.

Furthermore, generating hydroelectricity does not produce any kinds of greenhouse gases or smog emissions. Finding the balance between an efficient energy source that does not produce any greenhouse gases are crucial, especially in this day and time, where climate change is prominently becoming a large issue not just in Canada but all over the world. Between 1990 and 2013 Canada’s increase in emissions were caused by fossil fuels. Fortunately, there was a slight reduction from 2005 to 2013 and that was from the public electricity sector, for example, by using hydroelectric stations. If canada increased the percentage in which the hydroelectric stations supplied energy to, Canada could potentially cut down on greenhouse gas emissions and smog.

One of the most important ecological changes needed not only in this country, but globally would be the transition from fossil fuels and coal to renewable sources of energy like solar, wind, hydroelectric, and biofuels in an attempt to reduce carbon emissions, which in turn pollute the environment and contribute to adverse climate change. Even though renewable energy is able to regenerate, does not mean that it has no ecological footprint or that renewable energy is completely sustainable for our environment (Week 14 Energy Use & Transportation/Renewable Energy Sources). A renewable source of energy is usually one that does require us to mine away at the Earth to receive the source of energy (Week 14 Energy Use & Transportation/Renewable Energy Sources). Renewable energy is important for several different reasons. First, renewable energy has environmental benefits because it provides individuals with clean sources of energy and it reduces the impact that it will have on the environment (Why is renewable energy important?) Second, if we use renewable energy then we will have energy for future generations, such as our children and our grandchildren because renewable energy will never run out we will always have it, unlike other sources of energy that will eventually run out (Why is renewable energy important?). Third, renewable energy sources are important for the world’s economy and for jobs because the money that is spent on renewable energy in the United States will

When there is no water to produce hydro-electricity there will millions of people without electricity. Therefore, the amount of droughts that are caused by hydro-electric dams prove that they are not environmentally responsible. Hydro-electric dams are not an environmentally responsible form of energy because they will cause massive floods. The La Grande dam project in Quebec has already flooded over about 10,000 square kilometres of area around the dam. The hydro-electric dams are producing large amounts of floods which are starting to cover large amounts of agriculture and forestry. It is has also been said that if there are more dams created in the area it will cover up to 41,285 squared kilometres of land. Finally, the hydro-electric dams are not an responsible form of energy due to the amounts of floods they can create.

In the 1960’s and 1970’s a movement regarding the physical environment began, this movement focused on a few environmental issues and disasters caused directly or indirectly by pollution. As the years progressed, this movement grew into a multifaceted activist movement gaining more attention in the US, more often referred as “Environmentalism” or “Environmental Activism”. As the human race realized the physical environment is fragile and thus must be protected, scientists started to look for more efficient and ecologically safe energy sources. The introduction of renewable energy brought to light all of these issues, giving a viable alternative for the nation’s energy future, implementing resources that are naturally replenished and also, eco-friendly.

Humans have made significant discoveries in utilizing the countless benefits of water, one of the most important being the ability to use water to perform work. This is the concept of hydropower. Hydropower is using the energy of moving water to create power. This clean and renewable method of power generation is used all throughout the globe, and accounts for a small percentage of global electricity demand. Hydropower hasn’t always existed as the large scale dams that are abundant today. Hydropower technologies have been slowly evolving for many centuries.

The switch to clean energy in the United States and around the world is a difficult necessity that must be met within the subsequent five to six decades. The prolonged use of damaging fossil fuels and other unsustainable forms of energy are greatly damaging the planet. These sources of non-renewable energy are bound to run out in the following century. Millions of square kilometers of Arctic ice has melted so far, the sea level is rising, and the CO2 levels present in the atmosphere are drastically increasing (Chang). The transition to renewable energy must be met; however, this is not a process possible to achieve overnight. This change will require an extensive amount of resources and time but will reap many benefits to the users of this growing technology.

Due to the escalation in prices of the conventional sources of energy such as fossil and nuclear fuels and their harmful effects on the environment, there is a strong motivation to develop and utilize an alternative energy resources such as solar, wind, hydro and geothermal sources... etc cite{Karki2001}- cite{Fialho2015}-cite{Zhou2007}. In 2014, renewable energy overall expanded significantly in terms

I am submitting this proposal to provide some information on the long term effects of increasing demand for renewable energy. In this paper you will find information on how reducing the cost of energy can help economic growth and reduce the cost to maintain our standard of living.

The way that hydroelectric energy is created is actually pretty simple. In bodies of water where the water travels quickly, like at the bottom of a hill, there are turbines. Turbines are rotors that spin when the water goes through them, sort of like a windmill underwater. The turbine is connected to a piece of metal in a generator above land, so when the water spins the turbine, the metal spins and electricity is generated.

Hydro is derived from Greek origins meaning water. In other words, hydroelectricity is a form of energy generated by converting water into electricity. Hydroelectricity is considered a type of renewable energy due to its use of water. There is an unlimited supply of water in the world because of its continued and unending cycle: rain, evaporation and condensation. Ancient Romans were recorded as the first to develop the turbine method, which plays a major role in hydroelectric power plants.

When the topic of hydroelectric energy comes up many people wouldn’t know exactly what it is, or what it does. So what exactly is hydroelectric energy or more exact what does it do? Hydroelectric energy is one of the oldest power sources on the planet, generating power when flowing water spins a wheel or turbine. It was used by farmers as far back as ancient Greece for mechanical tasks like grinding grain. Hydropower is also a renewable energy source and produces no air pollution or toxic by-products. When most people guess what of hydroelectric, they think the Niagara Falls which was the site of the country’s first hydroelectric generating now a little history which supposedly according to the website the facility was built in 1881 when a man name Charles Brush connected a generator to turbines powered by the falls and used the electricity to power nighttime lighting for visiting tourists. America’s first commercial hydropower facility was built in 1882 in Appleton, Wisconsin powering lighting for a paper mill and multiple homes. But every state uses hydropower for electricity, and some states use a lot of it and according to the website it explained that over 70 percent of Washington State’s electricity comes from hydropower, and 11 states get more than 10 percent of their electricity from hydropower. Hydroelectricity provides about seven percent of the electricity generated in the United States and about half of the electricity from all renewable sources.

Water is a vital resource that supports all forms of life on earth. Water that is both clean and renewable is also used for the production of electricity (i.e. hydroelectricity through hydro plant) but depletion in rainfall, increase of sedimentation in reservoirs which have resulted in dropping of many storage levels of already build dams, increases in population, inadequate national water strategy and public’s careless attitude towards water preservation are major factors behind the water shortage in Pakistan which lead to hydroelectric crises. A great part of the world increment in renewable power supply is energized by hydro power. Throughout, the world power is the most generally utilized and
