How can alternative sources of energy be harnessed effectively? We are running out of our most important natural source of energy, fossil fuels. Fossil fuels are non-renewable natural fuels that were formed by the decomposition of animal and plants that lived up to 100-300 million years ago and humans cannot manufacture Fossil Fuels. The price of fossil fuels is also rising across the globe and when the fossil fuels are burned, it damages the already deteriorated environment. The burning of the fossil fuels is also the main contributor to global warming.
The light energy that I use comes both from the sun and from electricity. The energy from the sun is captured through solar panels that transform it and make it able to power the electric system of my house. The power plant of
Everything in the world living and nonliving are affected by the consumption of energy for example when using a electric hybrid vehicle we use less gas but then we use more electricity; we give up one resource for the use of another. Energy is made by coal, oil, and also can be made by natural renewable resources like wind power, biomass fermentation, and also solar power. Coal and oil are nonrenewable resources that we have to dig out of our earth to use and
What happens to the waste? For example, nuclear energy does not produce smoke or carbon dioxide so it does not contribute to air pollution. (Technology Student ,2009) Nuclear power is characterized by the very large amount of energy available from a very small amount of fuel. The amount of waste is also relatively small. However, much of the waste is radioactive and therefore must be carefully managed as hazardous waste.
Using fossil fuel in daily life for transportation, industry and producing electricity causes many problems to people, environment and animal. To preserve fossil fuels need large amount of money. The depletion of fossil fuel makes high cost and it keep rising that impact on people spending. Burning fossil fuels releases carbon dioxide, methane and carbon monoxide which causes air pollution and greenhouse effects toward people’s health, animal’s living and atmosphere. Because of these problems from using fossil fuel, there needs to be alternative energy.
Although fossil fuels get the job done, they are finite and also pose a great threat to the earth and the stability of the human race and economy, worldwide. They can be the catalyst of war and they pollute the earth significantly. The transition to green energy needs to be made quickly, and solar energy is a key player in the game. The Problem Fossil fuels, coal, oil and natural gas, are non-renewable substances combusted to produce energy. These substances have been formed over millions of years from pre-historic plant and animal matter which lies deep in the earth and has been under substantial amounts of pressure and heat for an indefinite amount of time.
Other advantages of nuclear energy include life-cycle emissions of carbon dioxide, nitrogen oxides and sulfur dioxide that are lower than all fossil fuel forms as well as solar photovoltaic and forestry waste biomass. Several key areas that nuclear energy are lower carbon dioxide (and other greenhouse gases) released into the atmosphere in power generation, lower operating costs, known, developed technology “ready” for market, large power-generating capacity able to meet only local residential, or office need but cannot generate power for heavy manufacturing and existing and future waste can be reduced through recycling and reprocessing. Nuclear energy is most definitely the future pertaining to discontinuing the use of fossil fuels. Though fossil fuels may offer that same 24/7 availability, nuclear energy has an unparalleled energy density of the fuel used. Just one uranium fuel pellet – roughly the size of the tip of an adult’s little finger – contains the same amount of energy as 17,000 cubic feet of natural gas, 1,780 pounds of coal or 149 gallons of oil.
This creates an atomic-level "friction" which produces heat (and light in some cases, such as a light bulb or glowing heater element). The important thing to remember is that an electron does not need to travel all the way through a wire for a device on the other end to receive power. When you turn on the tap to fill a glass, the water company doesn't have to pump a glassful of water from their facility all the way to your house - there is already water in the pipe, and they just need to add a little more on their end for some to come out your tap. If some electrons are pushed into one end of the wire, some will come out the other end because the uncharged metal in the wire already contains a sea of electrons(Matt Kramer of Wisconsin). For example, a circuit board has wires on
It comes in many forms such as heat, electricity, light, mechanical energy. Conventional energy sources for instance coal and oil are the main contributors to the global warming. Furthermore, these fossil fuels are not renewable. The good news is alternative sources of energy can replace the current technologies. These renewable energy sources are environmental friendly as they emit less carbon dioxide, compared to fossil fuels.
The turbine is a heat engine. It converts exhaust heat and pressure to rotation. This rotation is used to turn the compressor. The compressor takes in the draws in the outside air. It squeezes or compresses the air.
