Earth is endowed with natural resources that are essential for human existence. These resources are usually of geologic nature are can thus be extracted. Some of the earth resources that man extracts and uses include; energy sources for example oil, natural gas, uranium and coal; nonmetallic sources for example r...

...ring that each household is supplied with a solar lamp because unlike kerosene, solar energy is renewable. Solar energy is essential because it can be tapped from the sun thus reused over and over again.
Both renewable and non renewable sources of energy usually have advantages and disadvantages. Those who prefer natural gas claim that it is less polluting as compared to coal and other fuels since it leaves no residue. Moreover, it is reasonably priced compared to coal. Natural gas is not renewable can thus be depleted. Hydropower is cheaper to attain although it threatens marine life. It also requires the construction of a dam, which can be costly. On the other hand, crude oil is readily available and relatively affordable but its spills are usually a hazard to the ecosystem. Its extraction degrades the environment and thus a hazard to marine life (Sandra 2).

- The 2003 Northeast Blackout was a two-day nightmare that spanned from New York to Canada. This incredible event was not due to a storm, but computer and human error; affecting over fifty million people with estimated losses up to ten billion dollars and 11 deaths (Walsh, 2013). A loss of power turns inconvenience into a life-changing event when food in the refrigerator spoils, public transportation is useless, gas pumps are inoperable, and dark streets increase fear and anxiety. Even though power outages are a fact of life, few economies are equipped or prepared to provide their own power.... [tags: Fossil fuel, Alternative energy, Renewable energy]

- ... In this figure it is clearly shown just how the geothermal energy works. It is generally a collection of pipes running underground to raise and lift and put back in the hot and cold fluids found in the earth. First scientists discover a hot spot or area with a lot of volcanic activity, and then they drill into the earth very deep. Then one pipe leads straight up to the earth’s surface containing hot air, gas, or fluid of some kind coming from the earth’s inner core. This hot fluid, generally steam, is caught in the turbine that was created to run the plant.... [tags: turning natural steam into electricity]

- Renewable energy is energy that comes from a natural source of activity on Earth that is not depleted when used. There are a few sources of renewable energy sources that humans have put into use since the twentieth century; solar energy, hydroelectric energy also known as hydropower, and wind energy. According to National Geographic, “Solar energy is the technology used to harness the sun 's energy and make it useable” (Solar Energy 5). Today from all of the energy humans use about one-tenth of the energy comes from solar power.... [tags: Fossil fuel, Wind power, Renewable energy]

- 333745 Alternative Energy “If we put all our energy and resources into continued fossil fuel extraction, we will have lost an opportunity to have invested in renewable energy.” ( David Suzuki ) The past few decades, alternative energy has increasingly replaced the utilization of fossil fuels. Fossil fuels are composed from decayed plants and animals that are converted to crude oil, coal, and natural gas. As a source of energy fossil fuels are finite and have many negative side-effects, some of which include: incremented levels of carbon dioxide, output of toxic substances, heat-trapping gases that cause global warming, and by-products that pollute water-supply....

- Being amidst the wake of the technological revolution, we are faced with an ever increasing demand of energy resources on a worldwide scale, finding ourselves globally in an impending energy crisis. Industrialized nations, comprising the developed world, such as those of the United States of America and other European nations making up a mere 20% of the entire global populous, require close to about 53% of the global energy output, leaving the developing world with negligible resources to promote growth and development of their own....

- Renewable energy is energy that comes from sources that are restored naturally on a human timescale. This includes: sunlight, waves, tides, water, rain and geothermal heat. Roughly 16% of the world’s energy consumption is supplied by Renewable sources. Wind Energy Wind energy is the form of renewable energy that converts the wind energy from the wind currents into energy that can be useful to man. This is done using windmills (for mechanical energy), wind turbines (for electricity), sails (to direct ships) and wind pumps (for drainage or water pumping)....

- Energy it’s what makes the modern world work and what every human on this planet relies on. The energy crisis is clouded with fossil fuels that we use every day without think about their consequences. Energy can be obtained without burning fossil fuels that release global warm emissions into the atmosphere. Renewable energy is the future of energy and also helps create a new job market and millions of jobs. Renewable energy also helps reduce and prevent any more damage to our planet’s atmosphere, But people still ask the age old question of is renewable energy really worth it....

- Negative Effect of Current Coal Energy As the world is literally heating up, so is the pressing, controversial topic of climate change. The Intergovernmental Panel on Climate Change (IPCC) publishes a climate change report every 5 years; the 2014 report is the most alarming report thus far. The long report is the collaborative work of more than 800 climate scientists and governmental representatives. The report is shocking, and it should be. The IPCC concludes that human activity is the cause of climate change, just as smoking causes cancer.... [tags: Negative Effects, Current Coal Energy, Fuel]

- Currently, non-renewable sources based on oil, natural gas, and oil are harming the environment, animal’s and human’s health. These non-renewable resources are increasing the earth’s temperature, and the most challenge that confronts the future of our environment is the greenhouse effect that is caused by six main greenhouse gases; Carbon dioxide, Methane, Nitrous oxide, Hydrofluorocarbons (also known as HFCs), Perfluorocarbons, and Sulphur hexafluoride (United Nations Framework Convention on Climate Change)....
