Efficient use of Energy sample essay

Everyday individuals use different kinds of energy such as water, soil, mineral, forests and etc. But are these energies used up properly? Or are they used carelessly and ineffectively that would lead to pollution and global warming? During the earliest times, the life-styles of our ancestors were very simple. The air they breathed was clean. The streams were clear and free of harmful organisms. They used natural fertilizers for their agricultural crops. The surroundings were free of household throwaways.

Today, there has been a tremendous growth in science and technology. Such advances have brought about changes in terms of new products, improved equipment, and more effective methodologies. Unfortunately, this same technology which made life easier for us produced wastes which are now affecting the quality of our surrounding air, water, and land. Factories and motor vehicles send tons of pollutants into our air. Excessive air pollution poses a danger to our health and environment. It can likewise cause stunted growth and even death to our plants.

Out streams are polluted by discharges from industrial plants that use chemicals. Garbage and sink wastes are carelessly thrown in our surroundings. Synthetic fertilizers and insecticides pollute our land and farm products. Are we all aware of the extent of the damages brought about modernization? Have we contributed to such environmental pollution? What have we done to minimize such danger to our lives? How can we take care of our environment? We must undertake measures to conserve and preserve our resources and minimize utilization of energy before it’s too late.

Our fight against pollution is an initial step toward conserving our environmental resources and energy. We must all join hands for this common goal. Thesis Statement: This paper intent to discuss the different energies we used everyday and provide ways on how to conserve and efficiently used these natural energies to avoid shortage, pollution and global warming. II. Discussion The wealth of our country lies in its rich natural resources. We have lush forest resources, rich mineral deposits, vast fertile land, and sufficient supply of water.

They are the sources of durable forest products for constructing buildings, houses, and furniture. Our metal ores are the sources of precious metals which are used for jewelry, infrastructure projects, and other tools and weapons made of iron and steel. Our fertile plains supply us adequately with rice and other agricultural products. Out watersheds enable us to generate electricity, irrigate our farms, and satisfy our domestic needs. Moreover, energy from fossil fuels makes many industries run.

These fossils become a source of power responsible for the operation of some industrial plants and factories. Almost all our means of transportation like the buses and cars use gasoline and diesel. Airplanes and ships are also dependent on oil. At the same time, the burning of fossil fuels, particularly coal and oil, produces sulfur dioxide and nitrogen oxides which are hazardous to the atmosphere. Findings show that a single smokestack may produce as much as 500 tons of sulfur dioxide a day. When these gases combine with oxygen and moisture, sulfuric acid and nitric acid are formed (Jenner, 1999).

The rain will carry the acids to the ground (acid rain) which may cause the depletion of calcium and magnesium in the soil, elements needed by plants for the formation of chlorophyll and wood, or it may cause the release of aluminum in the soil, which are poisonous and can kill the roots of trees. Nitrous oxide or “laughing gas’ is a colorless gas with a sweet taste and odor that is used as an anesthetic in minor surgery that H2O is responsible for about 6 percent of the human contributes to greenhouse warming.

Methane or “cow gas,” on the other hand, makes up about 18 percent of human contributions to greenhouse effect. Cattle, sheep, goats, and other cud-chewing animals give off methane, in burps and flatulence as they digest (Cairncross, 2002). CFCs was discovered by Thomas Widgley Jr. , a chemist working at the Frigidaire Division of General Motors, used as coolants in refrigerators and air conditioners and aerosol propellants in spray cans, medical sterilizers, cleaning solvents for electronic components and raw materials for making plastic foams such as coffee cups.

CFCs are estimated to account for 14 percent of global warming. Experts said that what is happening right now is not a matter of adding a few degrees to the average temperature of a community. A rise of this magnitude may cause life, for without the environment, creatures on earth cannot survive (Davidson, 1999). CFCs are estimated to account for 14 percent of global warming. Experts said that what is happening right now is not a matter of adding a few degrees to the average temperature of a community. A rise of this magnitude may cause life, for without the environment, creatures on earth cannot survive.

Furthermore, with rising prices of oil in the world market, our government has explored the possibility if using alternate or nonconventional sources of energy such as geothermal energy. As of today a number of geothermal plants are being developed in different parts of the country. Geothermal energy is used mainly for generating electricity (Blackburn, 1987). In the home, electrical energy is used for cooking, air conditioning, and lighting, and for other electrical appliances. For entertainment, the radio, television, and video-cassette recorder need electrical power.

In order to survive the high price of gasoline, motorists must practice a number of energy-saving techniques such as putting off the engine when caught in heavy traffic, avoiding jack-rabbit start, and closing the windows during long drives to reduce drag. Regular checkup of the engine can result in efficient run. A nationwide campaign for conserving energy must be undertaken. Everyone must maximize the use of electrical energy in both public agencies and in private homes. At certain times, lights in parks must be alternately put off. Public buildings must not be lighted in the meantime that natural lighting is sufficiently available.

Street lights and those outside buildings must be put off during day. Lights for billboard advertisements must not be allowed during energy crisis (Duchin, 1994). At home, individuals can save on electrical consumption by putting off appliances such as lamps, fans, cleaners when not in use. A well-lighted schedule of continuous ironing or cooking at one time is economical. Set thermostat of room air-conditioning unit at moderately cool. A. Conserving Energy a. Conserving our Forests Every now and then we receive alarming news about our forests being denuded.

Big logging concessionaires indiscriminately cut down trees without undertaking reforestation measures. In some places big tracts of land are cleared by burning, thus killing old and young trees. The area is planted to short-term crops only to be abandoned later. Without trees, the soil is loosened and rapid erosion occurs. As a result fertile topsoil is washed away, which makes growth of other forms of vegetation almost impossible. We suffer great loss of timber, wildlife, and other forests products (Jenner & Smith, 1999). But the greatest danger is the occurrence of floods that cause losses of food, properties, and lives.

What is being done to check such wrong practices regarding our forests? Our government has designated a department that will run after illegal logging concessions. They are strictly prohibiting the cutting down of some trees. b. Conserving Water We need water for our home, for irrigating our fields, and for generating hydroelectric power. With such great demand for water, it is necessary that we properly use it. Are we aware of some practices that lead to loss of water? It is a common observation that many street pipes continuously leak for several days and nothing is being done to stop it.

At home the faucets that are left loose and that drip all day long could result in the loss of several gallons of water. Do you realize how water is lost on its way to our homes? The joints of pipes located along roadside may have been loosely connected, causing leaks (Jarrett, 1958). Sometimes fire hydrants are illegally opened and the water is used by some people for bathing and washing purposes. The proper authorities must strictly and consistently monitor faulty water pipes and maintain well-functioning ones to conserve water.

Fire hydrants, in particular, should be checked so that when these are needed in case of fire, they will readily be of help. Faucets that are defective should be repaired or replaced. In the long run, this practice is much cheaper than the water bill individual has to pay. Economize on water usage. Open the faucet only when ready to use. Do not keep the water running while brushing your teeth or soaping your hands. Reuse used water for watering plants and cleaning floors. During the rainy seasons, large amounts of water can be channeled to dams and reservoirs. On the other hand, we also lose water through siltation.

Siltation or sedimentation may occur in rivers and other reservoirs. This means the bottoms of reservoirs get filled up with mud and sand deposits. When this occurs, the amount of water that the reservoirs can hold is greatly reduced, thus, lessening the supply for irrigation purposes (McKee, 1991). Also, during heavy rainfall, they easily overflow and the surrounding areas become flooded. c. Conserving Soil One of the primary functions of soil is to absorb water, store it underground for some time, and make it available to the roots of plants. Soil is held together in place by roots of trees. Hence, cutting down of trees loosens the soil.

As a result, it is easily carried away by strong water currents. It is the topsoil or the most fertile portion which is washed away. The top layer of soil is likewise carried away by strong wind and is deposited in other places. At home, this action of the wind is evidenced by the gathering of dust in our furniture, curtains, and the floor. In cast open spaces, tiny hills of sand deposits are formed by the wind (Sawhill, 1986). With loss of fertile soil, food production is also lessened. The decrease in harvest may result to insufficient supply for the population. At the same time, the farmers’ income is affected.

Everyone must therefore undertake measures that will conserve and enrich our soil. This is very important in a country like ours, which has a highly agricultural economy (McKee, 1991). How can our government prevent forces of water and wind from eroding our soil? There are several measures that farmers resort to: • Prohibit indiscriminate cutting down of trees. Save the young pones which will be left when the mature ones are cut. Their roots hold the soil and erosion by water is minimized. • Plant cover crops. Low plants close to the ground prevent the wind from picking up the soil and carrying it to other places.

Bare land surfaces can easily be eroded by water and wind. • Construct terraces across the slopes to slow down the flow of water and soil to lower places. These graded steps will likewise stop the formation of gullies and retain rainwater. • Contour tillage consists of planting across rather than along the slope. The form of the land is considered in order to reduce erosion. • Strip cropping is another common practice wherein alternate rows are planted to cultivated and noncultivated crops. While the cultivated crops remove the minerals from the soil, the noncultivated crops build them up.

• Crop rotation is resorted to in order to regain the fertility of the soil. Leguminous plants containing nitrogen-fixing bacteria in their nodules are included among the plants rotated in order to restore the fertility of the soil. • At home, elevated surfaces can be protected from sliding down by lining the sides with big stones that are cemented together. This is called rip rapping. d. Conserving Mineral Resources Mineral resources, anther form of energy, are nonrenewable. Once they are removed from the rocks and then used, they cannot be replaced anymore.

Geologists tell us that mineral deposits in the crust are only about 1 percent. And this amount is not evenly distributed throughout the lithosphere. Our country is lucky to be endowed with useful energies. Since they cannot be replaced once removed from the rocks, everyone must learn to conserve them (Jarrett, 1958). They are the real natural wealth of the nation. The following are some of the steps that can be taken. • Strict regulation and control of mining operations by the government. • Lessen the use of expensive minerals by combining them with other substances to produce alloys.

Stainless steel is a product of the combination of nickel and chromium with the molten state. • Use a cheaper mineral instead of the expensive ones. Fro example, aluminum can be a substitute in producing wires instead of the more expensive copper. The advent of synthetic substances such as plastics and nylons lessened the usual demand for metal wires. • Reuse minerals over and over rather than throwing them away so as to lessen demand for new ones. • Undertake steps to protect them from disintegrating, such as treating metals to prevent corrosion.

The government should support and continue mine exploration activities to discover other energy or rich deposits in other parts of the country. Likewise, do research on better and improved utilization of energies should be continued so as to maximize the benefits from those that are already available. III. Conclusion In conclusion, the different energies we used up everyday are part of our day to day living. As users, everyone must responsible enough to use it efficiently to avoid environmental damages that would lead to climate change or global warming and conserve at the same time.

Consider the element phosphorus. Mined from phosphate ores, it is manufactured into fertilizers. It enters the plant tissues and we obtain it when we eat plant as vegetable. This is later excreted and joins the sewage system. The sewage system sludge can be used directly as fertilizer or soil conditioner. The wrong usage of our energies lead to climate change which is the most pervasive and truly global, posing a very real and serious threat to our environment. Climate change is the alteration of the pattern of global climate that may be due to human activity that alters the composition of the atmosphere.

Everyone should do something about it before it is too late and must not only depend on our government. Global warming may affect my health, if not resolved, and may take my life at risk if nature starts to avenge of what people doing. I need to recycle and reuse my solid wastes and encourage everyone to conserve our forests by not cutting down trees without undertaking reforestation measures. In addition, burning of fuel must be avoided because it can contribute to the possibility of having a global warming.
