From earliest recorded history Solar power has been important. The ancient Egyptians (and other ancient cultures) worshiped the sun as the ultimate source of power, and so who are we to challenge the concept. They were able to use solar energy to bake clay brick and build temples that stood for thousands of years. In fact over the last two or three thousand years we have more and more reasons to recognise it’s power over our lives. The trick, as always, is how to use that power wisely.
Leonardo daVinci in the 15th century also recognised the power of the sun and with a series of concave mirrors was able to focus the solar energy on a cooking pot and boil water. Five hundred years later we know you can do things like that but lack the patience and the inventive genius to actually do it!
In 1838 Edmund Becquerel recognised that some materials were able to turn sunlight into energy, and though he published his findings nobody was particularly interested. A few others played with these ideas but it was not till 1921 when Albert Einstein published his theories on photoelectric effect and was awarded the Nobel prize that many people even noticed its possibilities.
The fact is if it wasn’t for the need to power satellites it may have been entirely forgotten! The research into how to power the Vanguard 1 satellite in 1958 resulted in some quantum leaps forward for Photovoltaic cells (PV cells) and these cells have continued to be a part of satellite programs ever since.
During the 1970′s there was another surge forward when the manufacturing costs dropped from about $100 per watt to a mere $20 per watt, and this resulted in making them much more available for a range of new applications such as railroad and road warning signs, lighthouses and warning buoys.
During the last 15 to 20 years the price of PV cells has continued to fall and the efficiency has continued to increase, making them much more available to ordinary citizens to power holiday homes and other locations that did not have access to the national power grid. The most recent development has been the tax incentives offered by many governments to encourage domestic premises to install Solar panels with the excess production being fed back into the commercial grid.
Yet for all that, solar energy technology produces less than one tenth of one percent of global energy demand! Yes, we have made some great progress but here is still a long way to go.
So, where to from here? Solar energy facts are good to know, an important first step, but we also need to act on this information.
Shell Oil predicts that by mid century, up to 30% of the world’s energy could come from renewable sources. However, that will not just happen we will have to make it happen by accepting some short term pain to get that long term gain. What are you prepared to do to help?
This ebook, GREEN ENERGY 101, is an excellent resource for those who are interested in learning more about alternative energy. This e-book explains alternative energy systems, going into detail the different types of alternative energy available and what systems are available to homeowners as well as their advantages and disadvantages. Well worth reading!
Fossil fuels have been our source of fuel in the past, but it is now time to look forward helping to preserve a sustainable environment, planning for future generations using alternative power sources. One of those power sources is wind power electricity. We have been taking advantage of wind energy for many generations and now we have a modern day wind turbine which can be used on our homes.
Alternative energy solutions is about finding a balance between concerns for our planet and our unpredictable economy. A healthy environment is of utmost importance and we need to take steps so that we will still have it in the future. The flip side to that is watching our electricity bills continually increasing and it’s not always easy to pay each quarter. Somewhere in there we need to do more than we are to keep our electricity bills down and looking after the environment at the same time.
Which leads us to the idea of installing our own wind turbine.
1. Wind turbines have the capability of lowering electricity bills while preserving the environment. Having someone install one for you or even installing a ready made one, will also be helping the environment.
2. Building your own wind turbine is another way of keeping the set up costs down. Find a diy book with clear instructions, give yourself a few days and you can have your own wind turbine proudly displayed on the roof of your home, for a fraction of the price of a ready built one.
3. Consider your power needs, most likely one turbine won’t be enough to replace your power supply, but it will help reduce your overall bill.
4. Setting up a wind turbine will take investment of time and money. Work out how long you plan to stay in the home you are living in. Keep in mind, having a wind turbine attached to your home adds to market value.
5. Check where you might put a wind turbine on your home or property, making sure it is in a spot that has enough consistent wind to make it workable and profitable.
These 5 tips are just a few things to keep in mind in making your decision whether or not to purchase or build your own wind turbine. It is important to do your research, work out your needs and priorities, and then make an informed decision.

Most people I know are concerned for our environment, looking for ways to preserve it for future generations as well as saving themselves some money in the process. We need to be looking at alternative power sources, using clean, renewable energy. There are several alternative energy solutions available and the advantages of wind energy seems to be fairly high on the list. Why?
1. Dirty fossil fuels, like coal, need to be a thing of the past. It is time to move forward, thinking outside the box, to produce non harming wind power electricity.
2. Wind power electricity is an ongoing resource; as long as we have wind we can have wind electricity, there is NO short supply of wind. Some places are windier than others, so will be more of a benefit to those places.
3. Wind energy is very clean. There is no negative impact on the environment when using wind as an energy source.
4. If you able to follow instructions, then you can easily build your own wind turbine, harnessing the energy of the wind and saving even more money.
5. Having your own energy source during a blackout is certainly an advantage of your own wind energy supply.
6. Another advantage of wind energy is to build yourself a small wind farm with the option of selling any surplus electricity you generate back to the utility companies.
7. While one wind turbine might not produce enough electricity to get you off the grid, it will have an impact on your electricity bills. And these days, every bit helps.
I found this great youtube video, which I found most interesting. Although you might not have one like this in your own backyard, it is worth watching, comparing different noises in everyday life. Hope you enjoy it also.
With the rising costs of electricity, it is important that we do all we can to balance the budget. The environment is equally as important, preserving it for ourselves and for generations to come.
If you’re serious about learning more things you can do to protect our environment, download GREEN ENERGY 101, an excellent ebook giving informaton on different types of alternative energy systems and their components. It covers the concepts of solar and wind energy as well as the advantages and disadvantages of each. Recommended reading.
As the humanitarian emergency response to the floods in Pakistan takes shape, and with some of my friends from Australia involved, we can’t help but ask “Why are these things happening?”
The fact is, it is not just devastating floods in Pakistan, but a whole range of related natural disasters which also seem to be connected with uncharacteristically hot weather and fires in Russia, mudslides in China, melting ice shelf, increasing hurricanes an cyclones. There are some who would link this to global warming, deforestation and the increasing levels of greenhouse gasses.
Yet the reality is that thousands have died, millions are displaced and threatened with a whole range of diseases as a result. Time is running out and now is the time to reassess our role in these disasters and seek alternative energy sources which will promote health and healing of our planet rather than continue to destroy it through indiscriminate use of dirty power sources based on carbon fuels.
Last week while traveling from Sydney to Canberra (the national capital of Australia) I stopped for morning tea at Lake George and was amazed to find what looked like hundreds of wind turbines on the other side of the lake. These alternative energy generators were not there last time I went past so this must be a fairly new wind farm. In fact when I did some research I found that this area has become very popular for wind farms having several in that part of the state, with many others in the planning stage.
Yet for all this development and growth in this sector of the power industry, wind power still accounts for less than 1% of power production. Obviously we have a long way to go! The political spin doctors may be making grand plans to increase this to 25% by 2020 using a range of renewable energy technologies but I have my doubts as to how committed they are. The coal industry still holds too much power.
However, the current push for ordinary home owners like me to invest in solar panels for my roof, with the power being fed into the state grid is an indication that this state government is at least trying to get with the program and seeking some alternative energy solutions. Quite frankly it seems to me that it is only as ordinary citizens and home owners take some initiatives that governments will be shamed into doing more. Industry is becoming more aware of these issues, yet the demand to increase profit margins means many are only giving lip service to adopting cleaner, greener more energy efficient practices.
Together we must make a stand by doing what we can, starting in small ways such as investing in solar panels, purchasing more energy efficient appliances and adopting better usage practices. Only then will we have the credibility to influence governments and industry.
