Solar Energy - How Can We Use It? by Howard Puddy
... There are 4 main ways that solar energy from the sun is captured, these are:• Flat plate liquid filled solar panels for water heating • Flat Plate Gas filled solar panels for space heating • Photovoltaic cells for electricity generation • Passive Solar Heating Flat Plate Liquid filled solar energy panelsA flat-plate liquid solar energy collector is basically a metal box, usually insulated, that has a glass cover over a dark coloured metal plate (copper or cheaper aluminium).

Types of Solar Energy by Anne Clarke
... · Solar Updraft Tower – This is a type of solar energy plant in which air passes under an agricultural glass house, gets heated by the sun, and is then channel up toward a convection tower. It is used to drive turbines which generate electricity. · Energy Tower – This tower uses water, unfortunately, but it is also a good design and works in a similar way to the solar updraft tower. Water is sprayed at the top of the water. The water evaporates which causes a downdraft by cooling the air.

A Closer Look At The Alternative Energy Sources Of Solar And Wind Power by Gregg Hall
... An active solar heating system uses pumps to circulate water which has been heated by the sun. Passive solar heating systems use the nature of water to create circulation. This method relies on the fact that heat energy wants to move into areas of lesser heat. In generating electricity, solar power is harnessed by photovoltaic cells which convert the suns energy into electricity. These cells have been widely used to power calculators for decades.

What is Solar Power? by Anne Clarke
... In this case, solar power can be the saving grace—the only easy way to provide energy to a place that is not easily accessible to draw energy from other sources. What is solar power? It can be used for low-power purposes as well such as for items like battery chargers, hand-held calculators, and solar powered garden lights. What is solar power? Is it renewable? Because the sun will keep on shining, there will be no need to renew your primary source of solar power.

Solar Power How It Works by Anita Van Wyk
... 2.) Solar energy works by converting the sun's rays into heat with the use of solar thermal collectors for warming water, i.e. for the swimming pool. 3.) Solar energy works by converting the sun's rays into hot air for heating buildings with the use of solar thermal collectors. How do solar panels work? 1.) Rays of sunlight hit the solar panel (also know as a photovoltaic/ PV) and are absorbed by semi-conducting materials such as silicone. 2.) Electrons are knocked loose from their atoms, ...

Alternative Energy, The Dream And The Reality by Allen Goldstone
... Solar Energy Solar energy breaks down into passive and active solar. Passive is typically dealt with in the architecture phase of a building. Basically, passive solar is about orienting a building and constructing it with materials and techniques that take advantage of the sun’s lighting and heating abilities when it is dark and cold and shading it when temperatures are hotter. Active solar involves installing solar collectors that capture the sun’s heat and transferring it to a liquid for ...

Save On Energy Bills With Solar Home Heating For Hot Water by Lee Dobbins
... One of the latest inventions concerning solar energy is the solar pool heater. Pushing the envelope further, solar home heating can also be done. This was basically inspired by the experience of getting burnt once your skin gets in contact with water (primarily from hose) that has been sitting out on the sun for too long. This is called passive solar water heating. Before the beginning of the 21st century, states like Los Angeles and Florida have already taken advantage of passive solar hot ...

Here Comes The Sun: Solar Energy is Becoming More Attractive for Mainstream Consumers by Kavar Peter
... While California is the clear leader in promoting solar powered energy solutions (a program introduced in 2003 is promoting the introduction of solar powered energy systems into a million homes over the next several years) New Jersey and New York are next in line for solar investment. At the municipal level, many jurisdictions have introduced solar solutions for traffic and streetlights. 50% of the energy used to run the City of Sacremento’s water purification plant is solar.
