In the world today, alternative energy sources are becoming more and more of a necessity.Right now, the world’s energy demand is greatly increasing mostly because of population growth. Even though the rate of population growth is very diverse in different countries, the population doubles about every thirty years.The world energy being used is doubling every fourteen years. Still, the main energy source is oil. The other primary source of energy is coal. The only problem is that coal is even more polluting than oil, which could lead to climate change. These fossil fuels are not renewable. The good news is that alternative sources of energy can replace the current technology being used today. Renewable energy sources are environmentally friendly and emit less harmful gases, compared to fossil fuels. These are some of the reasons why the world is in an energy crisis. New technology will combine with clean energy sources to create a better future.
Energy comes in many forms such as heat, electricity, light, and mechanical energy. Conventional energy sources such as coal and oil are the main contributors to global warming. Many alternative sources of energy exist that harness natural forces and resources such as solar power, wind power, and geothermal energy.
From an environmental perspective in new technologies solar power is the most affective alternative source of energy. This energy is the light and the heat from the Sun which is harnessed to generate power. Created by converting the sun rays into electricity using solar powered. Solar panels change the sun's light that hit the panel into heat. Which is used to heat water, home, and swimming pools. Many other energy sources exist that are safe and natural.
Wind power is one of the best and oldest forms of energy that benefit mankind so greatly. In the past, people used wind to navigate water, to pump water into dry clothes. Today, humans use wind to produce electricity. In this...
