Solar energy is provided free by the sun and comes in two forms; light
and heat. Special technology is needed to capture this energy. Heat
from the sun can be used to heat water in our homes and buildings and
light from the sun can also produce electricity. There are two broad
categories of energy from the sun:
The map above is of global energy resources from the sun. The colors
show the average available energy from the sun on the Earth's surface
during 1991 to 1993. The scale is in watts per square meter. For
comparison, the dark disks represent the land area required to supply
the primary energy demand in the year 2011, using currently available
technology.
SolaMaps
is a social media solar web site with an interactive map showing home
solar installations (PV and Hot Water) from around the world. Check it
out an join the community to raise awarenes about this obvious form of
renewable energy.
Energy technologies utilising
the sun have great potential to benefit the world, and new emerging
processes, like Sliver
Cells will ultimately help drive
costs down. They can diversify energy supply, reduce dependence on
fossil fuels, improve the quality of the air we breathe, offset
greenhouse gas emissions, and stimulate economies by creating jobs in
the manufacturing and installation of systems. Technology using the sun
focussed in dish
concentrators has been around
for some time, although the technology is evolving and already
replacing some fossil fueled power requirements.
Energy Independence
Have you thought about a DIY
heating system using the sun? In many climates, a system can provide a
very high percentage (50 to 75%) of domestic hot water energy. Total
Solar Energy has some great
tips and advice for the the do-it-yourself project. If you are in a
rural environment you might also want to consider using solar
water pumps.
If you are interested in learning exactly how to generate power then
this is the perfect resource for you!
With the ever increasing costs of living there is no better time then
right now to start producing our own electricity. Whether you want to
simply reduce your power bills or completely eliminate them - Earth4Energy
has a solution for
you.
Why pay $1000's for solar
power or wind
power when you can build your
own professional system for
less then $200!
Earth4Energy is going to teach you everything you need to know about
producing your own electricity by using solar power or wind power. With
our complete step-by-step setup fully illustrated manual you will be
able to create your own power producing solutions in your own backyard!
With all the technical
jargon kept to a minimum (and
when necessary, fully explained), you will have all the answers to the
questions that have made you a little hesitant, in the past, to get
more involved in this clean, renewable form of energy production.
You'll learn about the various
components of a system -
batteries, inverters, charge controllers, photovoltaic panels, etc. and
how they connect to and interact with each other to form a complete sun
powered electric system.
Even if you're not the handyman
type or simply don't have the
time to do the actual installation, the knowledge gained from this
ebook will allow you to figure out the size of system you need.
Once your system is up and
running, this ebook will continue
to serve as an easy guide to the on-going maintenance of your system.
