After 6 years I've upgraded my solar hot water collectors on my roof. The original home-made experiment worked great, they were built into the roof but neede...

Types of Green or Renewable Energy
If the human race is to survive, we're eventually going to have to switch over to completely renewable energy. At the moment, most of our energy comes from natural gases, coal and oil based energy sources. These energy sources are both dirty and unsustainable.
What other alternatives do we have? These are the five main different types of green energy.
==> Hydropower
Hydropower is currently the largest producer of green energy, accounting for over 70% of our renewable energy production.
The way it works is that special installations are placed underwater, where strong currents of water will push through a mechanical instrument known as a penstock.
This "push" is then converted into electricity and fed into the energy grid.
==> Solar PV
Solar energy is another common type of green energy. There are two main types of solar power: solar power for homes and solar power plants.
Though solar PV has gotten a lot of press in recent years, there are a lot of problems still.
First of all, though the production of energy is more green than oil, the process of creating the materials solar PV is made of is quite toxic.
Also, to make your money back from the savings of a solar panel may take as long as ten to twenty years.
==> Wind Power
Wind energy is a stellar renewable source of power. The key to wind power is to place these energy generators in high altitude, high wind velocity locations.
The return on wind power is quite substantial. The only downside is that aesthetically they block the view from just about any angle because of their size.
That said, wind power is more cost-efficient than solar and easier to construct than hydropower.
==> Geothermal
Geothermal energy isn't applicable everywhere, but when it is the amount of energy generated can be very substantial.
Geothermal works by tapping into the earth's intrinsic heat. It turns that heat energy into power and uses that as electricity.
In order to use geothermal, a high-heat underground spot must be identified.
==> Biomass
Biomass is primarily the conversion of manufacturing by-products into electricity.
These by-products can include wood chips and fragments, leftover sugar, animal manure and anything else that's burnable.
Biomass can also include materials produced specifically for the production of energy (e.g. corn ethanol).
The biomass is burned and the heat energy is turned into electricity. Biomass is a great way of disposing of products that might otherwise become waste; but is unlikely to become a primary producer of our world's energy needs.
These are our primary sources of renewable energy. Of course, there are many other fringe sources of energy that are being researched all the time.
However, in order for a renewable energy to truly make sense, it needs to be both scalable and financially sustainable for investors. For the time being, the five listed above are the main sources of renewable energy.

Buying a Used or Discount Solar Panel for Greener Living
One of the main drawbacks of solar panels is their cost. Recouping their cost can often take as long as twenty years. That means that you'll essentially have earned zero profit in twenty years - you only start saving money from that point forward.
Instead of buying retail-priced solar panels, a great way to get more bang for your buck is to invest in used or discount solar panels instead.
Here are a few tips for finding and acquiring below retail rate solar panels.
==> Talk to Realtors in High-Networth Areas
Look for areas where there are many homes with solar panels. If you can find homes for sale that have solar panels on them, so much the better. But even if you can't, talk to realtors in the area anyway.
Make them an offer to purchase any solar panel that's on a property they're trying to sell. Realtors often find that prospective buyers don't want solar panels on their home because of aesthetic reasons, or they just don't want the extra cost.
It's a burden on selling a home, which means it can often convert into prime opportunity for buying a cheap panel.
==> Look for Out-of-Date Models
Another method for finding used solar panels is to contact manufacturers and distributors directly and ask for older models of their products.
Often times when a manufacturer updates their product line, they'll try to sell off all their old products at discount prices.
In fact, if you can find a distributor or manufacturer who still has solar panels from two models back, chances are you'll be able to get a steep discount on those solar panels.
==> Join a Discount Buying Group
Buying just one set of solar panels can be quite expensive. However, if you're buying ten to twenty sets of solar panels, you can get a much better deal.
Naturally, you're not going to buy that many solar panels on your own. However, if you join a solar panel buying group, you can often buy these panels together instead and get a nice discount off the price.
==> Always Get the Panel Tested
Before you pay for a used or discount solar panel, make sure you have a trained professional test it out. Often times the manufacturer or installer will be happy to administer the test for you for free.
Also check the solar panels for any clear damage. Check both the front and the back of the solar panels. In some panels, damage to the back is actually much more important than damage to the front, so don't make the mistake of only checking the front panels.
Seriously consider buying a warranty for any used or discounted solar panels.
Finding discounted or used solar panels isn't as easy as buying retail, but you can save a lot of money doing so.
