Renewable Energy: Yes or No? Joanna Fain Eng. 122 English Composition II April 15th‚ 2013 Although fossil fuels provide an inexpensive form of energy‚ they have been shown to pollute ecosystems‚ endanger animals and humans‚ are not sustainable‚ and cannot provide nearly the amount of energy that can be obtained from renewable sources. Fossil fuels do provide an inexpensive form of energy‚ but in contrast‚ they also pollute the atmosphere with greenhouse gases‚ thus contributing

photosynthesis of carbohydrates. Though living things emit carbon dioxide when they breathe‚ carbon dioxide is widely considered to be a pollutant when associated with cars‚ planes‚ power plants‚ and other human activities that involve the burning of fossil fuels such as gasoline and natural gas. In the past 150 years‚ such activities have pumped enough carbon dioxide into the atmosphere to raise its levels higher than they have been for hundreds of thousands of years. B. Causes Carbon dioxide is constantly

However‚ nuclear energy is considered as more reliable compared to other sources of energy. Moreover‚ energy sources can be classified as renewable and non-renewable sources of energy. Renewable energy sources are those which can be reused without depletion. Consequently‚ they cause less harm to the human health and less pollution to the environment. Wind energy is the energy from the wind and it is one of the best sources of renewable energy. Wind turbines are required to generate electricity. In addition

Our modern life today needs energy. World energy demand is more than available energy sources. Fossil fuels are running out every time it is used. So we need to provide new energy that can be harnessed instead of fossil fuel for today and tomorrow. Alternative energy This problem can be solved by LCOE‚ national grid‚ and new technologies like Crystal Solar and optimizing battery storage. Fossil fuel is non-renewable energy that will decrease when we use until it gone. It formed by dead plants

i CHAPTER 36: ENVIRONMENTAL CONCERNS LECTURE OUTLINE 36.1 Human Use of Resources A resource is anything from the biotic or abiotic environment that helps meet certain basic human needs. Nonrenewable resources are limited in supply. Renewable resources are not limited in supply. A side effect of resource consumption can be pollution. Land Use Change People need a place to live. Beaches and Human Habitation At least 40% of the world population lives within 100 km of a coastline

are the resources that cannot be reproduced/grown/generated or used scale which can sustain its consumption. Eg: Coal because it gets exhausted and long time to reform. When we use them and some other examples are LPG/nuclear/natural gas and fossil fuel are natural gas and nuclear energy. Although there has been many issues‚ people still use Non-Renewable Resources because capturing renewable energy still depends on use of non-renewable resources. For instance Sun is good example of renewable

Garrett Hardin’s Tragedy of the Commons 2) The Tragedy of the Commons is an economics theory by Garrett Hardin‚ which he believes that the depletion of a shared resource by individuals‚ acting independently and rationally according to each person’s self-interest‚ will affect the group’s long-term interests by depleting what is known as the common resource. This article has evoked a lot of strong emotions in myself mostly fear due to what basically Hardin is telling us is the past affects the future

statement: “Human activity‚ especially the burning of fossil fuels. It also answers inquiries of; is it a major contributor to climate change? Do I agree or disagree? From my research and readings‚ I‘ve concluded that‚ the foremost effect that burning fossil fuels has on our environment is the greenhouse effect‚ also known as global warming. Carbon dioxide‚ which is also known as greenhouse gas is released during combustion of fossil fuels and is the cause of this catastrophe. But yet‚ other

Renewable Energy Sources are defined renewable non-fossil energy sources including wind‚ solar‚ geothermal‚ wave‚ tidal‚ hydropower‚ biomass‚ landfill gas‚ sewage treatment plant gas and biogases. In Hong Kong‚ the energy consumption is highly relied on non-renewable resources such as coal‚ natural gas‚ oil etc. However‚ if we only depend on those resources continuously‚ it may have a high risk of deficiency. Because of the limitation of the Non-Renewable Resources‚ Renewable Energy Sources have

rapidly. Someday‚ it may provide a clean and abundant source of power. Solar energy is a very useful resource. Today 80% of the energy we use comes from fossil fuels and about 1% comes from solar energy. Fossil fuels are nonrenewable‚ that means that they are used up faster than they could be replaced. Also fossil fuels limited and cause pollution. Recently‚ there has been talk about creating a whole livable society in which all essential sources of man-made energy‚ which
