Wind energy is the motion of air molecules driven by the Earths rotation this causes difference in atmospheric pressure. The term “wind power” describes the air flow that generates mechanical power.
Wind Power Technology
We have been using wind power for various reasons since ancient times. In the Middle East, buildings have been specifically constructed to act as windcatchers for ventilation. Windcatchers can be used to manage airflow in and around buildings and harnessed in different ways: uni-directional, bi-directional, and multi-directional. The construction of a windcatcher in architecture depends on the direction of airflow at that specific location.
Further developments in wind power technologies has allowed us to build larger, robust equipment. This has enabled humans to explore far off lands through ship building and prosper through agriculture – wind mill technology. Read more
Renewable Energy is a sector which has experienced year on year growth, funders now have large appetites in funding renewable energy projects. If we change our habits, we can easily make use of renewable resources instead of raping the earth for fossil fuels. Using renewable resources can increase productivity and efficiency at low cost which can have a positive impact and a brighter future for generations to come.
World Governments have agreed to cut carbon emissions by 2% but unfortunately, some have cut funding in these areas. Countries like China are becoming a global superpower in renewable energy as they have recently cut their carbon emissions. Given the worlds incline to go green, funding renewable energy projects is a must!
The Sun discharges charged particles through space which hits the Earths magnetosphere. We see these charged particles in the polar regions where we see a green cosmic dance of these charged particles. Every 30-40 years the amount of sunspot activity on the Suns surface changes. This could be some suggestion that the Sun goes through seasonal changes bringing hot temperatures on to the Earths surface.
Solar energy is a free, renewable resource. Harnessing the power of the sun is still a relatively new idea. The ability to use solar power for heat was first discovered in 1767. The inventor, Horace de Saussure built the first thermal solar collector which he used to boil water and heat up food. In 1891, Clarence Kemp then patented a solar water heater to use for commercial purposes. We still use solar power in the same two forms today, thermal and photovoltaic.
