Introduction
We are dependent on energy for almost everything in our lives. When the outside temperature rises a little, we immediately switch on the air conditioner to keep our house cool. This is using up of energy. We have starting taking things for granted and we have started wasting energy unnecessarily. Energy is limited and hence to maintain the quality of life, it is important that we use our energy resources wisely. If we do not conserve energy, the energy will exhaust and we will have nothing to use.
Energy Intensity is considered a measure of the energy efficiency of a nation’s economy.
If a country has high energy intensity, this means that there is a high cost in converting ener...
Lab 4: Energy Conservation: Hot Stuff!! The purpose of this experiment is to try to find the original temperature of the hot water in the heater using the 60 degrees C thermometer. Use your 60°C thermometer, and any materials available in your laboratory, to determine the temperature of the water in the coffee pot. During this experiment we calculated the original temperature of a heater after it had been cooled down, and we did this by measuring hot, cold, and warm water, with a thermometer that had tape covering 60 degrees and up.
List the major sources of energy in the US from highest percentage to lowest percentage.
The path that the United States took to become the largest consumer of power in the world was one largely chosen by market forces and government intervention. The role of culture on the use of energy is negligible in comparison with the influences of economic and political factors. The choices to adopt several new methods to produce energy were caused by the backing that these energies had in creating wealth or saving money for those who used the new energy and by the backing of the government through direct and indirect subsidies. One can examine the transitions to coal, oil, nuclear power, and current transitions toward green energy in order to see that the market forces are the dominant factor in dramatic increase of energy consumption in the United States.
As the global population increases exponentially, having passed six billion in 1999, the world population is expected to be 8.9 billion by the year 2050. The worlds energy consumption will increase by an estimated 54 percent by 2025. Energy demand in the industrialized world is projected to grow 1.2 percent per year. Energy is a critical component of sustained economic growth and improved standards of living. One of the major requirements for sustaining human progress is an adequate source of energy. As the world’s technological enhancements and standards of living improve, so too does their appetite for electricity.
...one strives to use energy wisely, existing resources will last longer. Less damage to the environment will occur.
...to artificial costs of resources, it is humans that cause it to happen. Not only do these destructions cause global warming, they also put the health of many in danger as the climate often reflects the health of individuals. The gas permitted into the air by hydraulic fracturing and the chemicals from burning forests can all be breathed in and affect one’s health. Even the act of human terrorism, like the 9/11 terrorist attack in New York City, can cause green-house gases to escape into the atmosphere along with other air pollutants. Driving a car also contributes to the quantity of carbon dioxide emitted into the ecosystem. Individuals do not bother to use alternatives because they tend to choose the more convenient way of life. Human activities such as hydraulic fracturing, rice cultivation, fossil fuel burning and deforestation all contributes to global warming.
ways. The use of electricity will reduces the usage of the earth’s resources such as gas and oil.
Energy is a daily necessity we take advantage of without fully understanding the consequences of creating it. The electrical energy that we use as consumers comes from power plants that then convert other types of energy to electricity. The most common way this is done is from burning fossil fuels. The only benefits to this method is the low cost and the growing demand for oil, natural gas heating, and other products refined from fossil fuels. The repercussions of this cheap practice is the environmental and physical harm caused by the fumes and other byproducts of using fossil fuels. One main set back of this method is that people may not continue using it forever. Fossil fuels are nonrenewable resources that have come from millions or years
“Reducing your heat-trapping emissions does not mean forgoing modern conveniences; it means making smart choices, using energy-efficient products, and understanding which areas of your life generate the most carbon emissions.” (Ten Personal Solutions to Global Warming) A decade ago, global warming was not much of a concern as it is now. No matter how much we are informed about it , we as a society seem to ignore the future disasters that global warming will acquire. Global warming is a “global” dilemma and everyone has an obligation to help reduce emissions.
Household energy conservation is a very practical and realistic approach to conserving energy within our society. US households consume a tremendous amount of natural gas as well as electric energy. It has been calculated that the amount of energy consumed within the US increased exponentially from about 1850 to 1975. If energy continued to increase at this rate, we would be experiencing severe energy shortages in our current society. Luckily, steps towards conservation, including various energy regulations, have curbed that growth somewhat, brining the predicted 160 Qbtu/yr for the year 2000 down to around 93.8 Qbtu/yr by the year 1996. However, household energy usage is still a major issue as households consume about 38% of the total consumed energy and contribute greatly to natural gas consumption and issues such as global warming. Therefore, it is important that people understand how we use energy in the household and what steps can be taken to conserve that energy.

...e of efficient and environmentally friendly energy source that is used is by Norway. It got sixty four percent of its total energy from hydroelectricity. Starkraft is the largest producer of hydroelectricity in Europe which was able to contribute in building two hundred-sixty-three hydroelectricity plants in Norway, sixty in Sweden, ten in Germany and four in Finland. The introduction of hydroelectricity power plants in Europe benefit in superior efficiency, and a greater environment .
Imagine a life without lights, televisions, computers, trains, washing machine, refrigerators and microwaves. Imagine a planet so polluted that smog is in the air so bad that one cannot see very far, lakes and streams are poisoned, and land so badly scarred from people trying to find more energy sources. This may become reality in nearly future as a result of abuse of our energy resources. That reveals that energy is most important in our life, while a planet where we live is important too, a planet which effected by both generate the energy to meet our demands, and our use of energy.
Electricity has become a basic necessity for most people all over the world. We are depending on electricity for our everyday lives and if one day we did not have electricity we would have difficulty going through the day. I think we need to be more dependent on things that do not use electricity and only use electricity sometimes as a treat so just in case if one day electricity all goes away we could still live comfortably and still have a great life even without it.
In addition to, a huge issue with non-renewable energy is the fact that we get most of it from foreign countries. According to a recent study done by Energy Information Administration, “58% of our petroleum comes from outside the country”, this means as some speculate, that o...
