2011 Cxc Integrated Science Paper 2

Oil, gas, and fossil fuels have been recent controversial issues. There are cleaner forms of energy that could be used, but it is unclear what sources should be used and how to

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.

What is the main source of the increased levels of carbon dioxide in the atmosphere?

According to the graph, about how many times greater is the average American’s CO₂ output compared to the average Ukrainian’s?

Topic Disclosure: Today the primary source of fuel for the generation of electricity are fossil fuels such as coal, natural gases, and petroleum.

The energy transfer between the levels of the food pyramid is best described by which of the following statements.

Explain why we would draw different trophic levels in a pyramid with producers at the bottom and tertiary consumers at the top?

The purpose is to compare the methods of Electrical Generation in Canada and France. The outcome on my research is to provide information on the most and least sources of electricity generations in both of these countries. The energy sources that I am comparing are Liquids and Petroleum, Natural Gas, Coal, Nuclear, Hydroelectric, Wind, Solar, Geothermal, Tidal/Wave Power and Biofuels.

Our lives involve the emission of theses dangerous greenhouse gases (Bushnell 25). Carbon dioxide has increased to

Power production can come from multitude of sources with different types of power plant facilities each with some sort of unique need; these sources include coal, natural gas, nuclear, wind, water also known as hydroelectric, solar, geothermal and biomass (U.S. Energy Information Administration). These energy sources are broken down into one of two categories, renewable or nonrenewable.

In the United States and other countries, they have different fuels that people use in gas or electric. People use these fuels for the cars, help get the house warm and people use warm water to take a shower. The warm water using to wash clothes. Also, we use heat to dry our clothes in the dryer. In this paper, I am going to write about primary sources of fuels and what the similarities and difference in the fuel sources. Also, I am going how the fuel cause problems and the United States and countries can stop pollution.

There are about three universally used fuel sources for energy around the world which are: coal, oil, and natural gas. There has been a global increase in energy consumption throughout the world. Energy consumption is a topic that will impact the world. Greenhouse gasses are gasses that trap heat in the atmosphere, in turn, releasing carbon dioxide. This essay will discuss the common fuel sources, emissions, and total energy consumption by the United States and Brazil.

What has changed in the last few hundred years is the additional release of carbon dioxide by human activities. Fossil fuels burned to run cars and trucks, heat homes and businesses, and power factories are responsible for about 98% of U.S. carbon dioxide emissions, 24% of methane emissions, and 18% of nitrous oxide emissions. Increased agriculture, deforestation, landfills, industrial production, and mining also contribute a significant share of emissions. In 1997, the United States emitted about one-fifth of total global greenhouse gases.

Geothermal Energy The human population is currently using up its fossil fuel supplies at staggering rates. Before long we will be forced to turn somewhere else for energy. There are many possibilities such as hydroelectric energy, nuclear energy, wind energy, solar energy and geothermal energy to name a few. Each one of these choices has its pros and cons.
