The increased content of Carbon Dioxide in the air increases the warmth of our planet and is the main cause of the “Global Warming Effect”. One answer to global warming is to replace current technologies with alternatives that have comparable or better performance, but do not emit carbon dioxide.
We call this Alternate energy.
According to Oxford Dictionary, Alternative Energy is energy fueled in ways that do not use up natural resources or harm the environment.
Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels or nuclear energy. Alternative energy sources are renewable and are thought to be "free" energy sources. They all have lower carbon emissions, compared to conventional energy sources. These include Nuclear Energy, Wind Energy, Solar Energy, Geothermal Energy and Hydroelectric Energy sources. Combined with the use of recycling, the use of clean alternative energy sources such as the home use of solar power systems will help ensure man 's survival.
Solar Energy
Solar energy is the generation of electricity from the sun. It is split up into two types, thermal and electric energy. These two subgroups mean that they heat up homes and generate electricity respectively.
Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity, solar architecture and artificial photosynthesis, which can make considerable contributions to solving some of the most urgent energy problems the world now faces.
The Earth receives an incredible supply of solar energy. The sun, an average star, is a fusion reactor that has been burning for over 4 billion years. It provides enough energy in one minute to supply the world 's energy needs for one year. In one day, it provides more energy than our current population would consume
