Is It Time For Solar Energy to Get Hot?
Is It Time For Solar Energy To Get Hot? By Tim Phelan Solar energy has been around for quite a while and most people don’t think about it much except for the ones who are already into renewable sources of energy. Environmentalists have always...
Photovoltaic Panels - Harvest the Sun Light
There is a lot of energy in sunlight and that energy can be
converted to electricity with photovoltaic panels. These panels
are made up of several photovoltaic cells which are constructed
of treated silicon which creates an electrical charge...

Photovoltaic Systems - Energy from the Sky
As people search for alternatives to fossil fuel energy, solar
energy emerges as one of the cleanest and most practical sources
of electricity. Solar panels can be installed on rooftops or any
area that receives a lot of sunshine. The solar panels consist
of a photovoltaic system that converts the energy of the sun
into electricity.
Photovoltaic systems have existed since the 1950s but only in
recent years has the technology matured to the point of making
it a viable alternative to power utilities. Indeed, most solar
systems do not replace the utility company, instead they work in
conjunction with it to produce extra electricity that can be fed
back into the grid.
One of the main problems with solar power is storing it for use
during non-daylight hours. Batteries can be used but they are
expensive and have a limited life span. As an alternative,
excess solar electricity can be fed back to the power utility
company for a credit, and then power can be drawn when needed.
In a sense, the utility company becomes the storage device.
Most municipalities have legislation requiring power utility
companies to
David Alan Grier's 'Sporting Life' On Broadway
The stand-up comedian and star of <em>In Living Color</em> was recently nominated for a Tony Award for his portrayal of Sporting Life in the opera <em>Porgy and Bess</em>. "I think the character of Sporting Life is a salesman so he has to be flamboyant, the life of the party," he says.
Thirty positive actions for a sustainable Earth
There are many ways we can use our human energy to lighten the load on natural resources and tread lightly on our home planet. Check how many of these you do already: 1. Recycle and re-use Wherever possible, separate waste into compost material,...
accept electricity produced by solar panels or wind
turbines. This system benefits everyone - there is less
dependency on fossil fuel power plants and electricity costs are
reduced for owners of photovoltaic systems.
Photovoltaic cells produce electricity by using specially
treated materials such as silicon that convert light into power.
They can be of almost any size and are suitable for providing
electricity for small items such as calculators or watches right
up to complete industrial complexes. Because they can be wired
together, an array of solar cells can produce enough electricity
for residential or commercial needs.
The main requirement, of course, is sunlight. This makes solar
power most practical for southern areas such as California and
Arizona. But it can also be used in more northerly areas as a
backup power system. As the technology advances, photovoltaic
cells are able to produce usable amounts of electricity even in
low light conditions.
