As our planet descends rapidly into an impending energy crisis, we need to end our dependency on fossil fuels and non-renewable energy sources as soon as possible. As their name suggests, non-renewable energy sources cannot be replaced, and once used, are gone forever. Renewable energy sources, by comparison never run out. The three main sources of renewable energy solutions are solar, hydro and wind energy. But, what are these and how can we benefit from them?
solar energy : The energy from the sun is the most abundant energy source available on Earth. Not only is it free, in most parts of the world it is also extremely plentiful. Wherever possible we should make use of this fantastic free energy source. There are many solar power solutions available today that you can easily employ at home. Not only will this help you cut down on energy bills but you will also be contributing to a greener, cleaner world.. Solar power solutions comprise of solar cookers, solar heating systems, solar lighting systems, solar dryers etc.
In addition to being very cost effective and environmentally friendly, solar energy systems have many other advantages. They are low maintenance thus saving time and effort. You can also gain a very good return on your investment in a short time frame. This means that, after a short time, the systems will have paid for themselves, and will continue to provide completely free energy for a long time thereafter.
Hydro – electric power: Hydro-electric or water energy power is an extremely efficient renewable energy source. Although generally produced on an industrial scale, small hydro power generators are now available to enable you to harness this renewable source. It has been estimated that 90 percent of the electrical energy produced by renewable resources is produced solely by hydro power. With large scale hydro schemes dams are built to help generate electricity by creating a head of water that, when released , unleashes a huge amount of energy that can be turned into electricity by large turbines.
There have been some concerns about using this hydro-power because large schemes can destroy large areas of natural habitat as they are turned over to lakes.
Wind energy : Windmills have been used for thousands of years for a variety of uses. They helped tow boats and pump water as well as grind grain to make flour. Eventually in more modern times, they became a source for generating electricity.
Windmills, both large and small have proven to be extremely effective at producing large amounts of cheap electricity. When used on a smaller home-based scale, they can actually, very often, completely replace conventional power sources. An excellent renewable source of energy, the wind energy will go a long way in promising a good future to generations to come.

What renewable energy sources are viable for the typical home?
Unfortunately we live in a conservation area so solar panels or wind turbines on the roof are out.

Conservation area means you will not be able to install any energy generation at your home. Depending on where you are you may be able to buy in your energy from a green source.

Not many reasonable options right now for me either. But apparently in about 5 to 10 years infrared panels which collect infrared radiation very efficiently will be common, they even work at night.

Realistically, I don’t think many renewable energy sources are currently cost effective for most size homes. However, the government does offer rebates and tax incentives to make these options more attractive. Solar seems to be the most popular. The panels are easily installed (in most circumstances), look nice, and have a good life span. Wind harnessed every isn’t feasible for a house (unless you have a mansion with a lot of land to put a wind turbine).

Do you have a pool? Because I just had solar heating put in! http://www.arosaenergy.com/residential-pool-heating.html They did a great job now I can swim all summer without worrying about my bills! You can Call Arosa Solar they might be able to help you 866-276-7222 I was really happy with them! Good Luck!

In town it is best to focus on conservation. Not as frilly, but just as if not more effective.
Pool heating is an excellent option as previously mentioned. We use Fafco panels and a differential temperature controller to stop the flow of water through them at night:

Wind is not a good option in town, no matter how you slice it.
Many home owners associations/"conservation areas" just need educated. We make a drawing for our customers to show them what the final solar installation will look like. Many installers will do this. You can then take the drawing to the governing party and show them the facts.
Hope That Helps!

Wood heat is probably the most effective renewable energy for most homes. You can use a wood stove, furnace or boiler. Pellet stoves are another option. Stoves can burn wood pellets, corn or wheat. If your furnace burns #2 fuel oil you can burn biodiesel instead of petroleum fuel. Can you add a greenhouse to the south side of your house for passive solar heat?

Have you checked with the your local planning office, I am sure you will be able to put solar panels on the roof.
Hot water solar panels are the cheapest way to do it, they give the greatest return, for the amount invested.
Groundsource heat pumps with either shallow or deep collection pipes may be an option.
