Wind is a renewable resource that can create electricity and this is why there have been many wind turbines installed throughout the country. These turbines use the winds forces to turn their aerodynamic blades, which then turn to a rotator to create power. The rotator is connected to the main shaft and spins a generator to create the electricity needed.

Cost-
Normal cost for the wind turbine system between buying and installing up to 1kW can be anywhere between $2,000 and $10,000. Larger systems can be up to 6kW and cost $20,000- 50,000.

Grants-
The grants for wind turbines aren’t like the current grants for solar power. There are Renewable Energy Certificates that can be obtained, (pending certain conditions) that can be traded in for money. Shop round for the best deal and take into account the total purchase including installation.

Savings-
Currently, there is not enough data from domestic wind turbine installations to provide a reliable energy and carbon saving figure.

Maintenance-
Although they have a working life of around 20 years, wind turbines still require regular checks every few years to ensure they are working to their full capacity.

Who is it suitable for?
Wind turbines work best when they are at a high level, so it is recommended that it be on a mast or tower. The ideal land for this resource is one with clear exposure, elevated land, free from excessive turbulence and land obstructions like buildings or trees.

You also need to consider visual issues, noise and conservation implications of the wind turbine on your property.

There are some small scale wind turbines designed for urban locations, however none have proven to be super energy efficient.

You can get some financial support, but there are also other ways to improve the energy-efficiently in your home without waiting a long time.Once certain energy-saving elements are installed, it will cut your households carbon footprint but it will also save you money on fuel bills.

The solar powered cells are one or two layers of semi-conducting material (in most cases it is silicon), which then uses the light to create an electric field across the layers, causing the electricity to flow. The PV cells do not need direct sunlight, but the greater light intensity the greater electricity flow.

Costs-
Prices of solar panels systems will vary considerably depending on the type and size of system you wish to have installed. The structure of your home will also have an impact on the price range.

As a rough guide, a typical PV system will cost somewhere between $5,000 to $20,000, most average systems being around 1.2 and 3kWp. Payback periods can be lengthy but the major benefit of having this system is that they don’t generate any greenhouse gas to create electricity and save about 455kg of carbon dioxide emissions per kWp per year.

Grants-
Currently you can get grants of up to $8,000 for 1kW or greater solar PV cells to be installed. Each grant will be subject to a household annual income of $100,000 and will differ from home to home.

Savings-
The savings will differ depending on the level of on site consumption and/or value of export tariff.

Maintenance-
Cells connected to the grid will require little maintenance but will still need regular checks by a qualified professional to ensure the wiring and components are working to their full potential. Stand-alone systems will need less maintenance on other components such as batteries.

Who is it for?
You can get a PV system generally if you have a sturdy north facing roof with no trees or building that would overshadow it or if the roof surface has shade for parts of the day. The roof must also be strong enough to hold the heavy PV systems.

To save our energy and our environment, environmental activists and scientists have come up with a form of renewable energy that allows us to re-use the resources we already have and hopefully, will never run out of.

Fossil fuels were first used mainly because they are convenient, take less space and are affordable. But the more we use them, the more they burn a hole in the ozone layer and the less energy fuel we have.

But renewable energy attempts to get us to use the natural resources we have to continue to have a clean and healthy environment. The renewable energy process involves taking natural resources and making them into a product we can use for power.

There are many methods and ways to do this, each evaluated to see which is the best result and which will be best for the future.

Renewable energy sources are better for the environment and is a more practical way of saving the world we live in. Renewable energy can be created from the sun and water, but the only thing is, is that this can be unpredictable for the changes in the seasons.

But this energy would be a good idea to have as a first priority and have the fossil fuels as a back up.

Indoor solar lighting-
Solar lighting can be used inside your home, shed or even gazebos and is easy to install. The best thing about solar lighting is that you don’t need to change light bulbs all the time, saving time, money and the environment.

A solar panel will be installed in the area that will attract the most sunlight. Once the sunlight hits the panel, light will be reflected and will give light to the house. After the sun sets, you will still have enough energy in the panel to power the lighting.

Outdoor solar Lighting-
Outdoor solar lighting is different, as you will need more energy and light in the darker areas. There are many different types of outdoor lighting that need high energy lighting to run. These include flood lights, pond or pool lights, security lights, spot lights. Most of these can be solar powered and will still run effectively.

Solar powered path lights are a popular form of outdoor lighting and allow people to be guided through the dark. Lighting that is sensor activated will also reduce power and save energy. These lights can work even when the power is out.

Although this lighting may not be as bright high energy lighting, it is an economical and practical choice for yourself and the environment.

One of the ways that you can help fight this problem is by sourcing your household energy from environmentally friendly, renewable production methods.

This is colloquially referred to as ‘green power’ and it is one of the most important steps in tackling climate change.

Almost all of the major electricity providers in Australia have a green power option, and if you are happy with your current energy provider then you should speak to them about the green options they may have available.

The Australian government has an accreditation scheme setup, which is designed to let consumers know which companies are up to scratch when it comes to providing renewable and environmentally friendly energy.

Some companies will claim that they have a green option, or multiple green options, when this may not actually be the case. For this reason it is always worth checking if the company is fully accredited.

If you are interested in taking your commitment to renewable energy one step further, you could consider decking out your home with solar panels, and make it energy independent.

In fact, if you install solar panels on the roof of your house and they generate more power than you consume, you can contribute to the greater problem by feeding energy into the power grid!
