LED Bulb Research paper Just a few years ago a 60 watt equivalent LED bulb cost upwards of $50 (LaMonica, M n.d.). You’ve probably heard about how expensive LED bulbs are, but there are many benefits to using them that you might not know. Today you can get a 60 Watt equivalent LED bulb for about $10-15 (LaMonica). Some benefits to using LED bulbs in your home are reduced energy costs, longer bulb life, and they’re environmentally friendly. You may have to pay more upfront for an LED light bulb, but did you know that the average homeowner could save a total of $238 a year in energy costs alone by switching to LEDs (Howard, B. n.d.)?
Solar energy is a non-pollutant, cost effective, maintenance free, life span of up to 40 years; however the upfront cost is enormous, and not everyone can afford the cost to put the stylish panels on their roof tops. Many jobs would be lost at the oil field however more jobs would be created by installing other methods of
Renewable energy sources are hydropower energy, biomass energy, geothermal energy, wind energy and solar energy. Renewable sources of energy can be used over and over again and also they generate much less pollution, both in gathering and production. But they are not as popular as the nonrenewable sources as can be seen in Figure-1. Figure-1: Renewable Energy Sources vs Total Energy Sources Solar Energy As you can see in Figure-1, the sun is probably the most important source of renewable energy available recently years. We are able to harness the sun’s energy and use it to help heat our buildings, our water, and also to produce electricity.
The History of the Solar Powered Water Heating System Barbarann INF103: Computer Literacy Egad! November 19, 2012 The History of the Solar Powered Water Heating System Earth is in danger and humans are the culprit by living in a highly industrialized world dependent on fossil fuels and other non-renewable resources. Not only the environment is being harmed, finances are influenced as the cost of fossil fuels continues to rise. Luckily, there are alternative sources of power like the sun. A solar powered water heating system is the easiest initial investment in renewable energy a person can make (Ramlow, 2007).
vvvvvvvvCONS - Nuclear power is not a renewable source of energy. High-grade, low-cost ores will run out in 50 years - It is not "greenhouse gas" free, producing more emissions than some renewable power sources such as wind - It would take at least 10 years and several billion dollars to build Australia's first nuclear power station - Plants are potential targets for terrorists attacks; smuggling of radioactive material is on the rise; no complete solution to the disposal of radioactive waste has been found PROS - Greenhouse gases from nuclear power are about 12 times less than gas power stations and about 30 times less than coal stations - Australia has a large percentage of the world's high grade uranium ore that could
Knowing that we have renewable resources, the opposing voices argued that we need to use less fossil fuels and more of the renewable resources. They do have a valid point, with them bringing up the statistic that we are using fossil fuels 100,000 times faster than they are being formed and many people
As we are theoretically reaching “peak oil”, “peak gas” etc. as well as the occurring of global warming and a number of environmental issues, the call for more “clean”, “sustainable” renewable energy has been increasing dramatically. However, some critics argue that renewable energy such as wind, solar, biomass, alone can not sustain the world in the future. In this essay, I will argue that renewable energy is not a viable way for replacing established energy sources by analyzing the geographic and natural limitations, impacts on ecosystems and the efficiency on cutting greenhouse emissions of renewable energies. The real solution should be reducing energy consumption.
Switching to alternative sources such as electric cars can help pull this number down significantly. Electric cars are more affordable as Electricity is cheaper than gas, and can come from renewable resources such as solar and wind power. Electric cars pollute less than gas-powered cars, which makes them better for our environment. Electric cars are much more reliable and require less maintenance than gas-powered cars. By using domestically generated electricity rather than relying on foreign oil, we can achieve energy independence and will no longer need to engage in costly wars in the Middle East to secure an energy supply.
Countries should use nuclear energy because it is eco-friendly, it can produce a lot of energy, and it is the best energy resource we can use so far. People started to develop nuclear energy soon after the discovery of radioactive element such as radium. When people first discovered radioactive, they thought nuclear energy is unfeasible, because, though radioactive elements can produce a lot of energy, but high energy produced means short half-live for radioactive. However, in 1938 the idea of being impractical changed, because three German chemists discovered nuclear fission (Nuclear Power). “Nuclear fission is the process of breaking up atoms; the process will generate an enormous amount of energy in form of heat” (Nuclear Power and the Environment).
The Benefits of Nuclear Energy It is imperative for the international community to look into other energy sources due to increase costs of fossil fuel and the ever-increasing demand of electricity. One of the most beneficial alternatives to fossil fuels is nuclear power. Some of the reasons that make nuclear power so beneficial include it’s efficiency, cleanliness, and safety. These reasons are emphasized when compared to fossil fuel electricity production. The unrivaled benefits of nuclear power demonstrate why it should be used as the primary electricity source for the future.
