Essay about alternative energy sources
Preet Kaur Preet Kaur Alternative sources of energy Subject: Sciences MYP5 Mahatma Gandhi international school Word count: Alternative sources of energy Energy is what we call; work, it surrounds us in every aspect of life but the challenge it to use it to constructive ends.
The extraction, production, and development of these sources have contributed to the many issues with the environment. What most people don't understand is that global warming is happening now, and we are already feeling some of its destructive power.
Importance of alternative source of energy
This increase resulted in an accelerated depletion of the resources of fossil fuels such as coal, oil, and natural gas See figure 2. When a crisis hits the U. For centuries, fossil fuel was, and still is the most conventional source for generating energy This problem is the need for alternative energy sources which can be converted into electricity because the main energy source currently used is coal and the coal deposits will not last forever. In cohesion with this concern, the current uses of fossil fuels are a concern as the environment pays an incredible toll for our overuse of this resource. A person on average will throw away 4. The main reason for the heavy debate is not the energy source but rather the mining of the energy source through the process of hydraulic fracturing
Indeed, the sun for many years has provided heat for the earth whereby the energy it produces warms the earth directly and also indirectly. Solar cells are also often referred to as photovoltaic cells.
There are many advantages and disadvantages to hydropower, though there are more advantages.
This means as our demand for these fossil fuels increases our supply will decrease dramatically. These sources of fuel have worked fine for the world, until now.
Alternative sources of energy essay in english
Wind power is one of the oldest forms of energy that benefited mankind so greatly. These sources for practical purposes will last forever. In every business and in every home we use energy to light and heat our houses, and offices and to make our machines and vehicles work. The same process is used to cool the steam in this cycle as the other. There have been intense debates on whether this source of energy is worth using up the water from the lakes and rivers, something that is important to protect the animals and plants. In smaller scale, it is used to heat houses, water and in cooking. Solar cells have been considered a promising potential solution to this problem, but issues with conventional photovoltaic cells based on crystalline materials include high manufacturing cost, poor durability, and limited versatility. Not only has solar power brought use to 21st century technology but also uses technology for its advantages. Energy Information Administration, www. However, the idea of solar energy as a sustainable, renewable form of electricity, is on another level completely. Alternative energy sources cause little or no pollution and are widely available. The longer the world waits, the harder it will be to replace these fuels before they run out Natural resources advance the use of hydrogen because it makes up 90 percent of the known universe, it also is the most abundant element on Earth. One of the most important issue in the context of an environmental state of the planet is energy sources. The demand for energy is more popular than ever, while the sources for energy are quickly vanishing.
One of the alternative energy sources is solar power. That is the kind of world the future may be like if there is not an overhaul of how electricity is obtained.
Going green for some means recycling and planting a garden, for others it means alternative sources of energy; in this case alternative sources of energy for transportation Fossil fuels have to be burned in order to produce energy.
