Alternative Energy Sources
The population recently reached the sis billion mark and will continue to grow at an exponential rote in the future. As the population increases, so will the demands for resources like food, water, and electricity. Renewable, clean, and efficient power is increasingly important as limited fossil fuel sources slowly disappear, and pollution becomes more of an issue. However, the industry has already begun to answer many of the tough questions about where our power will come front in the future.
Today, there are several ways of generating power. Nuclear, hydroelectric, wind, solar, coal, oil and gas, are the most significant methods.
Many people believed solar power would solve the world’s energy problems. After all, if we could harness all of the sun’s energy that hit the earth in a one minute period it could power the entire planet for a year. In fact, only a hundredth of a millionth of one percent of the sun's power even arrives at the planet. Solar power is already used to heat pools and homes and photovoltaic cells convert sunlight directly into electricity. Unfortunately, although these cells are becoming more reasonably priced, they are expensive in comparison to the amount of electricity they create. They would be unreliable as a sole source of power. ,
Wind power is one of the most promising prospects for the future. It is inexpensive and fairly reliable. Wind turbines are placed high above the ground to take advantage of faster, less turbulent air flows. It is the fastest growing renewable energy source in the world and globally it accounts for more than
31.000 megawatts. Wind power is absolutely pollution free and wind turbines can be placed in remote areas like mountain tops and out at sea. In addition, they require little maintenance.
Nuclear power is also an interesting alternative to fossil fuels. It is cheap, efficient, and clean. Nuclear energy is generated as fission unleashes the energy stored in the atom. Many people fear the nuclear meltdowns like the one that occurred in Chernobyl, a plant in the former Soviet Union. However, these events are rare, and more people have died in fires and coal mine accidents. Unfortunately, the disposing of nuclear waste will eventually become a problem despite safety techniques. Scientists use safe containers to store the waste, but as it accumulates it would be hard to store and keep out of the hands of dangerous people.
Hydroelectric facilities utilize water, o renewable resource, to turn turbines. They are absolutely pollution free, but can disrupt the river and ocean habitats where they are constructed. Many dams are now built with fish ladders to help salmon who migrate upstream to make their yearly mating journey. Yet, many fish can still be caught in turbines, and changes in the currents and structure of a river con severely damage the habitat. In addition, hydroelectric dams require a powerful river and suitable areas are scarce. Therefore, hydroelectric power would be unable to grow with demand.
Hydrogen fuels are also o promising alternative for the future. Hydrogen fuel cells, which combine hydrogen and oxygen to produce electricity, are currently used tor HASA’s space vehicles because they are light weight and release a lot of energy. In fact, they release 7 times more energy than an equal amount of cool. 0n top of this, hydrogen can be burned purely to release only water. Hydrogen is one of the most abundant elements on the planet and the most abundant element in the universe. The only down side is that hydrogen on earth is most often trapped in water, biomass, fossil fuels, and some inorganics.
There are several.
The traditional sources of power are fossil fuels. They include coal, oil, and natural gas. Of them all natural gas is the cleanest while coal generally causes the most environmental pollution in the form of smog, soot, acid rain, and toxic metal compounds.
