About Wind & Solar Energy
Wind and Solar energy have a great amount of contribution to our environment and Earth, they are both renewable energy resources and they are taken from natural resources like our Sun and wind. The most special thing about Wind & Solar energy is that they are not found only in Canada, but globally, as it is a very larger and impactful industry. Wind and Solar energy help to reduce climate change as these energy resources can make electricity naturally, without fossil fuels. Wind and Solar energy are important parts of Earth.
They can be used for many different things like creating electricity, grinding grain, pumping water, powering windmills, heating houses and water and many more uses! Wind energy has been harnessed by human civilizations from thousands of years ago, some of the earlier forms of windmills had used wind to crush grain or pump water, now, in 2016, wind turbines utilize wind to create electricity. Wind turbines nowadays are also much more complex than they ever were before as they have 8,000 different components of a wind. Solar energy wasn't a new idea, it was first invented in 1938, but the idea was turned down as Solar energy was too expensive, but people still think it is too expensive, Solar energy costs approximately $20,000 to $40,000 to get installed in Ontario.
You cannot necessarily trade Wind & Solar energy with other countries as the Wind and Sun are resources that every country has access to. They doesn't make many products, but two main products of Wind & Solar energy are windmills and solar panels, which both make electricity.
Installing/Producing Wind & Solar Energy
How Wind Energy Is Made
In order to install a wind turbine it costs approximately $48,000 to $65,000. A wind turbine works the opposite way a fan works, as wind energy is not made by using electricity, unlike a fan. The wind turbines use wind to make the electricity, then the wind turns the blades, which spins a shaft, that connects to a generator, allowing Wind energy to make electricity.
How Solar Energy Is Made
As I said before it costs approximately $20,000 to $40,000 to install Solar energy. Sunlight consists of photons that radiate from the Sun, causing the photons to be in the sunlight. When the photons hit the silicon atom in the PV cells, the photons transfer their energy causing them to lose their own electrons. Then you need to collect the stray electrons and make an electrical imbalance in the cell. This will be in the form of a slope as it will cause the electrons to flow in the same direction. After two different types of silicon is created, p-type and n-type silicon. P-type silicon has electrons that are missing which ends up leaving holes in their places. N-type silicon has spare electrons. When the two materials are placed side by side, n-type silicon, which has spare electrons, will fill in the holes in the p-type silicon, which has electrons that are missing which ends up leaving holes in their places. That causes the n-type silicon to be positively charged and the p-type silicon to be negatively charged, creating an electrical field across the cells.
The Decreasing Usage of Wind & Solar Energy
The usage of Wind and Solar energy has sadly decreased globally and in Canada. Recent data has shown that in the United States of America, renewable resource consumption has increased in the past 3 years by 0.621%, but in Canada between the years of 2008 and 2015 wind and solar energy usage has decreased, wind energy usage has dropped down to 3.2-million megawatt-hours (MWh) in 2014, that means that wind energy usage has dropped by 1 million MWh. Solar energy usage has also decreased, in the year 2012, 260,000 MWh of energy was produced using solar panels, that had dropped by 9,000 MWh in 2014, leading to 251,000 MWh of solar panel energy being used.
If we want to save and sustain our planet we need to start using Wind & Solar energy as they both help reduce the usage of fossil fuels and they are a renewable way of making energy for many different purposes. The Oil Minister of Saudi Arabia, one of the most oil exporting country, had predicted the end of fossil fuels by the end of 2040 or 2050. He had also stated that Saudi Arabia would start developing solar power.
Although in some countries like Germany the usage of energy increase and goes to its peak during the summer, but the usage of energy decrease to a low near December and January.
What We Need To Change For A Better Tomorrow
In order for a better tomorrow, we need to start working today. We need to change the fact that we rely on fossil fuels as our resources, we also think that Earth is an abundant resource, because it's not. The usage of fossil fuels will not last forever as they are non renewable resources.
Wind & Solar energy are resources that can be renewed and made again as they are near us. In order to sustain Earth we need to start using Wind & Solar energy more as they are made from resources that can be produced again and they don't take as much work than extraction oil and other fossil fuels from Earth.
In conclusion, Wind & Solar energy have an importance to Earth and to us. These two energies will help us for a brighter tomorrow. Although, we may or may not utilize these energies they are the next step to rejuvenating Earth.
