Breakthrough Breakthroughs : Clean Energy And Its Challenges Essay

Why are fossil fuels not renewable? America uses up more gas than nature can produce, therefore, one day in all probability the U.S. will run out of gas. “People use them faster than nature could make them. One day the world will run out of fossil fuels” (Fossil Fuel Power pg. 24). “Some scientists believe the United States has enough coal to last 250 years. They think the country has enough natural gas to last about 100 years” (Fossil Fuel Power pg. 24). “Scientists expect that earth’s supply of petroleum will be used up within the next 75 years” (Energy Crisis the future of fossil fuels pg. 12). Many people believed and still do believe that one day earth will run out of fossil fuels.

Firstly, and put very simply, fossil fuels are non-renewable! Once the finite deposits of brown and black coal are exhausted around the planet there will be no more energy generated by this process. Current estimates predict that all known coal deposits will be exhausted within the next 120 years.

As the Law of Conservation states, energy can be neither created nor destroyed (The Secret Lives of Energy). That means that an energy source has to be use in order to generate the energy needed. It is common knowledge that the pollution caused by the use of fossil fuels over time is making society live in a contaminated world. In addition, the cost of the use of fossil fuels is increasing and becoming too expensive, forcing people to find alternate ways in which they can pay less for the use of energy. The use of fossil fuels over time has increased to a point where the remaining reservoirs have decreased by a large margin. On the other hand, renewable energy is

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.

The United States relies heavily on fossil fuels as its main source of energy and with the limited supply, we 'll have to develop and utilize alternative sources for clean, renewable, cheap and effective energy to power this country and the world into the future. It will be important for the health of our planet to utilize renewable resources that have no greenhouse gas emission. Out of necessity the world will eventually need to stop using fossil fuels for energy.

The United States is the largest consumer of nonrenewable resources in the world. In the United States the primary source of energy comes from 3 different resources. These resources are petroleum, natural gas and coal. The three of these resources make up over 90 percent of the energy consumption of nonrenewable resources in the United States. These nonrenewable resources are considered fossil fuels that are not costly when it comes to extracting them from the environment. Fossil fuels are a large contributor to the air pollution than any other resource.

Non-renewable energy is produced from sources that cannot be replenished for thousands of years once its depleted. In short, it takes thousands of years for non-renewable energy sources to form. They are usually found buried deep inside the earths crust. Fuels like coal, natural gas, crude oil, and nuclear fuels. Coal, natural gas and crude oil are collectively called “Fossil

The nation’s current energy situation is in bad shape. We have nearly depleted the planets resources of fossil fuels that are non-renewable. Energy4Me.org defines nonrenewable resources as are energy sources like petroleum, propane, natural gas, coal and nuclear power. These resources have taken millions of years to

Geothermal energy is the use of the Earth’s heat as energy, hence geo- (earth) and -thermal (heat). Geothermal energy is generated in the Earth’s core by the decay of highly unstable radioactive particles, which create heat when decayed. Geothermal energy then moves toward the surface through the mantle, mostly near where tectonic plates (the geological divisions of the Earth) meet via convection currents. This energy heats holes in the Earth that are filled with water, which are known as reservoirs. This makes steam, which can be piped up to either district heating systems (to heat houses, businesses, etc.) or geothermal power plants (to make electricity which are sent to houses, businesses, etc.). One place

The term, “non-renewable energy,” is at its most basic form, means that the sources of energy will eventually one day run out and not replenish itself. Non-renewable energy comes in many forms. For example: coal, crude oil and natural gas. These sources are categorized as fossil fuels, meaning that they were formed in the past due to natural processes from dead organisms. Non-renewable energy has been proven to be very beneficial to the US, however, many people argue the negatives are not worth the benefits.

The power of electricity is available to anyone with a simple click of a button. The methods of obtaining the energy used to develop that electricity are commonly debated topics. One of those methods is using geothermal energy, or the Earth’s naturally produced heat.

The world after running out of fossil fuels would be a horrible place for living. life would be hard and harsh. This is the case for us if we couldn’t find new energy resources. Nowadays, many countries are reliant on energy from conventional sources like crude oil, natural gas, and coal. These sources are limited and they eventually will run out at some point in the future. Considering this fact and increasing demands for energy, the search for new energy resources is reasonable and it should be taken seriously. In recent years, renewable energy resources have proven as an interesting alternative to conventional energy resources. Renewable energy resources like wind energy, solar energy, and hydropower result from the natural process and

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

Solar radiation, planetary energy and geothermal energy are the three forms of renewable energy available on earth. Radiation from the sun is the highest source of energy and the obtainability of these sources alters. In a nuclear fusion process in the sun, hydrogen is transformed into helium. It is in the form of electromagnetic waves that the surface of the sun radiates this energy. This will

Energy is a crucial necessity and with the ever increasing need for it and the high and fluctuating prices of oil, researchers are constantly coming up with newer and more sophisticated alternative sources of energy. However, energy comes at a cost, as it is either expensive or it possesses high health risks. This essay presents the concept of energy by discussing the two major types of energy, the various forms it could take, including renewable sources of energy, energy conservation and above all it talks about the safest and cleanest alternatives.
