One of the largest sources of free energy, both in the amount and strength of that energy is the sun, and here are the top three ways to exploit solar energy.
Let’s face it, without the sun, there would be no life, so it is impossible to underestimate the importance of the sun to our planet. Not only to stay alive as we know, it also provides thousands of times more power in a single day than we humans use in an entire year.
This means that we can only tap into a small fraction of the energy that is available to us, so we could do a much better job of harnessing energy from the sun than we do do. But, until we come up with new ways to use solar energy, these are the top three ways to harness that energy.
1. Generating solar power
This is the way to making solar energy that most people are probably familiar with using, or at least, one that they think is called as solar energy. That does not mean that people generally understand the details of how it works, but they are certainly aware that solar panels used to generate electricity.
What it has done is another matter. That would be through the use of a scientific discovery called “photovoltaic effect”, the work of a French scientist named Edmund Becquerel, who at that sunlight react with certain materials such as selenium was a small charge of electricity.
[heeft19459002] This discovery has been refined over the years and today made of silicon solar cells are connected together in a metal frame on a panel, which, when combined with a number of more panels to form a matrix, can be enough electricity to power electrical appliances and equipment of a house.
PV (a popular abbreviation for photovoltaics) technology is embraced as one to fight the best ways for us and hopefully beat the effects of carbon dioxide emissions and global warming, and make more people use of the advantages for both themselves and the environment.
2. Using solar thermal energy
Solar has been around for centuries, although most people do not realize that that’s the name given to it when they hear such things as the ancient Greeks through glass and mirrors warmth of the sun ages ago. This was the beginning of thermal solar energy.
Nowadays, the most common uses for solar thermal energy for hot water and heat for homes and businesses and to heat swimming pools. Hot water heaters usually use a storage tank to hold the heated water, and solar pool heaters recycle the water from the pool through collectors that heat water and transfer back to the pool.
3. heating and cooling, passive solar
When you open your curtains in the morning to the sun, use of passive solar energy in to make its simplest form as possible. Passive solar energy is the only means by which we enjoy as the sun’s energy for heating and / or cooling to provide spaces and buildings.
passive solar energy can be as simple as just shown, but is usually a little more complicated as a technology and design function. Passive solar systems are designed to the energy of the sun in what is known as a thermal mass, which is basically a kind of material, such as certain types of wood, concrete, etc., who holds the energy for later use as heat when the temperature cools strike.
Passive solar can also be used for ventilation via solar chimneys.
These are the most common methods currently used for solar energy, and combining these methods would be a great way to make use of a home almost completely energy independent. But, together or separately, they can go to reduce a long way towards helping the energy costs and carbon emissions.
