GET RUNNING HOT WATER, NOT HIGH RUNNING COSTS

December 15th, 2009 No comments

Water heating is the largest single source of greenhouse gas emissions from the average home (excluding the family car).It’s also power hungry, using up to 35% of a home’s energy. 
The cost of installing and running a solar hot water system is less than most people realise.  The fact is, solar hot water systems generally pay for themselves within two years from installation and then the real savings start adding up.
A solar hot water system can save up to 90% of an average household’s hot water energy requirements.It can also save up to 3.4 tonnes of CO2 emissions from an average household per year.There are factors to consider such as the direction of the roof, quality and location, but in essence, the sun can provide the bulk of the energy requirements for domestic hot water.Conventional gas or electricity sources can make up any shortfall.  
The cost of electricity is growing and there is greater emphasis on finding renewable energy sources.When one counts the cost that generating electricity has on the environment, the argument for solar power is even more convincing.
Solar hot water has been the subject of massive technological development in recent times.  Consumers now have a choice between roof or ground-mounted systems, which are suitable for any weather conditions from below freezing to the harshest desert heat.
Solar hot water can be installed anywhere, new buildings and old.It is a relatively simple process to replace an electric hot water system, and many governments around the world are encouraging and incentivising householders to do so.
In Australia for example, eligible property owners, landlords and tenants are rewarded with generous government rebates when they replace their electric storage hot water systems with solar.The Australian Government is currently offering a 600 rebate per eligible installation of solar hot water to help people reduce greenhouse gas emissions.It is currently estimated that the average family can reduce their annual energy bill by up to seven hundred dollars by installing a solar system.  
Perth solar hot water company, Solar MyWorld, have experienced a huge increase in demand for their systems since Government announced the rebates.The company says people are making lifestyle adjustments to meet growing pressure to reduce their carbon footprint, and they have seen a consequent increase in demand.  
A study commissioned by the Australian Government, ‘Energy Use in the Australian Residential Sector 1986-2020 projected a 56% increase in residential sector energy consumption from 1990 – 2020.Water heating was the only major energy use predicted to decline over the study period, predominantly due to Government and State energy programmes.Water heating energy use reached a peak in 2002 at 92.4 petajoules (PJ) and is anticipated to decline slowly to 8.5PJ by 2020. 
Solar hot water is one of the simplest lifestyle changes that people can make. There are no reasons not to go this route.It is both cost-effective and low maintenance and on top of that, is kind to the environment too.Plus, a solar hot water system that has been correctly installed using quality parts should last at least a quarter of a century.That should warm you up!

Wind Energy The Pros And Cons Of Building Your Own Wind Turbines

December 1st, 2009 No comments

Wind energy, a lot of people are ardently jumping on the bandwagon and constructing their own wind turbines for their home. But is it truly worth it? Can they seriously save that much money? The answer is yes, they can and so can you.

Now I don’t want to give the impression that this form of energy is the do all and end all to your electricity needs. While it is a fantastic way for the average home owner to cut their electric bill by up to 80%, you do have to keep a few points in mind.

To begin with, you will probably need to have more than one turbine to produce enough electricity for your home. Of course that will depend on the size of the turbine you have, and your energy requirements. But generally speaking, a homeowner will need several small turbines to generate enough electricity so they can kiss their utility company goodbye.

One more consideration is where you live. Everyplace gets wind but many places, such as Chicago, get more. If you live in an area where you don’t get a lot of wind, possibly you have a lot of trees, or you live in a valley, you won’t get as much out of your turbine.

Alternatively, since a wind turbine can be built for a few hundred dollars and since a lot of homeowners see a substantial savings from just one turbine, it will most likely still be worth your while to invest in this environmentally friendly, completely renewable, free wind energy source.

It can be a excellent family project to build your very own wind turbine. The kids will learn to be grateful for the environment as they grow up.

For any person who is worried about the environment, as well as their own financial health, utilizing wind energy can be a very cost efficient way to help the earth and themselves.
