The last time that UNSW researchers were able to make a breakthrough with solar technology was in 1989. The UNSW researchers’ work was funded by the Australian Renewable Energy Agency (ARENA), and backed up by Australia-US Institute for Advanced Photovoltaics (AUSIAPV). The new material developed by the UNSW researchers uses a custom optical bandpass filter to capture light from the sun that is otherwise wasted on current photovoltaic panels. The worldwide demand for energy is on the rise, while traditional sources of power are on the decline. The California Institute of Technology (Caltech) is also developing a new material that could harness the power of the sun efficiently.
The Massachusetts Institute of Technology (MIT) has also developed a new technology that could improve the efficiency of converting sunlight to electricity. MIT’s new solar technology also has the same concept with UNSW’s in terms of reusing the wasted solar wavelengths that goes straight through today’s photovoltaic cells. The material they used in making the device is made of carbon nanotubes and photonic crystals.
MIT’s work was demonstrated as part of the university’s Solid-State Solar-Thermal Energy Conversion Center, one of the 46 Energy Frontier Research Centers around the world. How we can reduce greenhouse gas emissions by using alternate energy sources and reducing, re-using and recycling the resources we currrently use. Meat is one of the biggest contributors to our carbon footprints and Australians eat a lot of it. Kangaroos digest food differently to cattle and sheep, so they don't produce as much methane.
Services are nearly always lower in emissions than goods, so going to a concert is better than buying a CD. Buy durable goods that don't need to be replaced so often, rather than disposable or cheap things that will wear out quickly. Repairing your old car or washing machine is usually better than buying a new one, as each new product takes energy to make. Changing your electric water heater for gas or solar could cut your electricity bill in half. Living with other people is a great way to reduce your footprint, because you share appliances, hot water and heating and cooling in your house. Smoother driving rather than speeding and braking can save one third of your car's greenhouse gas emissions. Almost all of the greenhouse gas produced by transport comes from the petrol you use in your car. It is predicted that emissions from flying will increase four-fold by 2050, as more people will travel by plane. Making bricks from mud and earth takes less than one per cent of the energy it takes to make an ordinary brick, so much less greenhouse gas is produced. However you'd have to plant trees over an area the size of Australia to offset the whole world's greenhouse gas emissions for a year. Trees grow slowly, so it takes many decades after you plant them for the greenhouse gas to be absorbed.
Today humans are heavily reliant on fossil fuels such as oil, coal and gas to generate electricity. Some gyms or dance clubs are already collecting our energy and using it to power their lights and music. Opponents claim it is dangerous to the environment and there's risk from misuse to produce weapons. Hambantota is to get a $190m solar power plant, after Australian company Energy Puzzle Group reached an agreement with the Sri Lankan government.  The plant will cover 8 and a half acres, will generate 150MW of power per annum, and is expected to be fully operational by 2015.
However, at least at first, the majority of the energy produced by the plant will be for export, with Energy Puzzle targeting India, Japan and the Gulf States.
Featherson said that Sri Lanka was the perfect location for the investment: “The BOI has created a conducive investment environment in Sri Lanka.
However, this painful phenomenon is not without benefits — hoses turn into miniature geysers thanks to solar thermal energy (STE), one of the oldest and greenest renewable energy sources known to man. Medium-temperature collectors, which operate at temperatures significantly higher than the ambient air, have also found a niche heating homes and businesses. The US built nine such power plants, between 1984 and 1991, in the Mojave Desert in California. While such solar farms take up a large amount of space, they have the capability to deliver an equally large amount of energy. I should note, I just pulled those EROEI figures from Wikipedia - there are probably better, more up-to-date figures around, looking at different types of solar thermal. That’s why when some researchers from the University of New South Wales (UNSW) were able to convert more than 40% of solar power into electricity, scientists considered the result a milestone. When the sun’s wavelengths tap the silicon atoms on solar panels, the atoms’ outmost electrons get recharged. In that year, renewable energy researchers in the university were only able to convert 20% of solar energy to electricity. The new record of converting more than 40% of solar power to electricity was confirmed by the National Renewable Energy Laboratory at their satellite testing facility in the U.S. According to reports, solar scientists in the university are building a new material for photovoltaic cells that are not made of silicon but of pure metal.


MIT’s technology involves a high-temperature material whose infrared radiation would be collected and converted by photovoltaic cells. One of MIT’s researchers explains that conventional silicon-based solar panels do not take advantage of all the photons so what they did was insert a two-layer absorber emitter device between the sunlight and the conventional photovoltaic cells. Once the sun hits the device, it will be able to emit light wavelengths that the photovoltaic cells can easily absorb.
He is running this site since 2009 and writes on various environmental and renewable energy related topics. The total greenhouse gases that humans add to the air cause warming and other changes to our climate.
If we shared out the right to produce greenhouse gas fairly across the world, each person would get around 8 tonnes.
The greenhouse gas produced for each bottle of water is equivalent to driving a car for two kilometres.
A bag of individually wrapped lollies, for example, will have much more packaging than loose lollies. A trip out to the Museum doesn't produce much greenhouse gas, especially if you come by bus. Try buying local products as products from other parts of the world required fuel and energy to transport them here. You can cut costs by turning down your thermostat by 1°C (for heating) or turning it up (for air conditioning).
A window loses ten times as much heat as a wall in winter, and in summer a window can add as much heat to a room as a small radiator, so use curtains to keep heat in or out. Older fridges are often much less efficient then newer ones, so if you have an old fridge in the garage recycle it or only switch it on when it's really needed.
Keep your tyres pumped up to the right pressure, and take out all that stuff you are carrying around unnecessarily in the boot. It is possible to capture the energy from your movement and convert it into an electric current. On a much larger scale, we may soon be able to harness the power from crowds at concerts, train stations or sporting events. The sun provides us with enough energy every hour to provide the world's energy needs for a year. This produces electricity which can be fed into batteries or directly into the national electricity grid. Not all areas have enough wind, and some of the windiest places are in natural beauty spots or are a long way from cities where people need electricity. The movement drives generators to produce electricity which is fed into underwater cables and brought to land. This heat is a constant source of energy and can be used to produce geothermal (meaning 'earth heat') electricity.
It is suggested that it could meet all our energy needs, is less dangerous than the current process and produces lower levels of radioactive waste. We hope the second phase will begin around mid 2016,” Energy Puzzle Chairman Patrick Featherson said yesterday. There is also a very high level of education and engineering expertise within the country, which is highly underutilised. They lay there, quietly baking in the hot summer sun, just waiting for some dumb schmuck to come along and try to take a sip — then BAM! Unlike photovoltaic technology, STE harnesses the sun’s rays to generate heat rather than electricity.
In 1760, Swiss naturalist Horace de Saussure devised a solar oven built out of a half-inch tall pine box, topped with glass pane. To make domestic hot water, it used a trio of water tanks set in a sunny greenhouse on the south wall of a home. Even as the world economy exploded with the advent of the internal combustion engine, STE technology continued to evolve. Solar water heating, like Kemp’s Climax, uses solar water panels to continually heat a large supply of water. Still in operation today, they together produce about 354 megawatts annually, enough to power a half million homes. Industry experts like Fred Morse, a senior advisor to Spanish power utility, Abengoa, believe that were the Southwest’s 226,000sqkm of open, flat and sunny land were used for a solar farming, it alone would generate 11,200 gigawatts of power. Watched a show on discovery channel ages ago about the parabolic mirrors heating molten salt.
According to reports, the technology used by the Australian researchers consisted of a custom optical bandpass filter that captures more sunlight that is otherwise wasted on current commercial photovoltaic cells that are attached on rooftops.
When the electrons on the panels get enough charges, they move rapidly throughout the panels to generate electricity. Apart from university researchers, some engineering companies are also helping firms become greener.
He lives a green lifestyle and is often looking for ways to improve the environment around him. Simply cutting down on the amount you buy is the easiest way to reduce your carbon footprint. So instead of cutting back our greenhouse gases, we could just plant lots of trees to mop it all up, or pay a company to do it for us.


Bicycle dynamos have been doing it for years, but more sophisticated technology can be built into almost anything we move or move on. Solar power refers specifically to the conversion of sunlight into electricity through photovoltaic cells or solar concentrated thermal technologies. However, there are plenty of areas in the world where turbines can make a big contribution to electricity needs.
With more investment, its capacity could triple worldwide but there are issues with space and environmental impacts.
About 25 countries use this type of electricity, but only a few use it for more than 15 per cent of their electric needs.
If enough investment was made, these technologies could more than match the capacity of nuclear energy.
In residential use, STE usually boosts the efficiency of water heaters, heat pumps, and absorption chillers.
Placed in sunshine, the glass pane and enclosed area worked in tandem to concentrate incoming solar energy and prevent its escape (aka the greenhouse effect). But the current, reasonable estimates put the total installed STE-collection base at just 35 gigawatts by 2020. The customized optical bandpass is able to convert the wasted solar resource into more electricity. The problem with this setup is that despite absorbing some of the sun’s wavelengths, most solar panels today do not absorb longer wavelengths. Harry Atwater, head researcher of the project, said that adding electrons to the atoms of metal nanostructures and then charging them up would change the resonance frequency.
It's cheap and if you freeze a half full bottle and then top it up with water, it will stay cold all day. Every year Australian households waste more than $1000 buying things they never use or only use once.
Usually, when you pay a company to plant trees, they promise to look after the forest for 99 years. The challenges are how to capture it cheaply and efficiently and then develop ways of storing the electricity. Some companies are now making large turbines with blade diameters of nearly 130 metres, which is about the length of a rugby field.
The energy of waves, tides and flowing water can also provide electricity and it's generally a more predictable source than solar or wind power.
This is due to the fact that the height and frequency of waves is variable, and few places are suitable for building large wave farms.
It can be difficult and expensive to extract this energy, especially if the rocks are too far below the surface.
This allowed the system to continuously heat larger quantities of water for a houshold throughout the day. These systems, commonly used to heat pools, operate at or below the surrounding air temperature.
Systems like these can provide domestic hot water, or they can be used with heat pumps to efficiently heat and cool entire houses.
The only testing facility of its kind in the US, the Solar Thermal Test Facility at Sandia National Laboratories can focus six, 11.5m parabolas, each comprised of 82 mirrors, at a seven-inch wide target and heat it to over 650 C.
The glass for the mirrors is expensive to produce and producing glass also uses a crap load of energy.
So perhaps you are simply time shifting your greenhouse gases, instead of hanging around in this century, you are paying for them to go into the next. Without storage, we can't have electricity when the sun's not shining - not much use on a cold dark night. The turbines generate electricity from the mass movement of water by tides.Tidal energy is not yet widely used due to challenges of local geography and engineering. Water is usually dammed and as it falls from a height the force of the falling water moves turbines which generate electricity.
Some of the more creative new applications of these systems can be seen at the biennial Solar Decathlon competition, a contest among college students to design and build a home that achieves net-zero energy consumption.
Even that lower estimate significantly alter the amount of electricity generated by renewable sources. The company is able to maintain solar-powered facilities including Heliostat Central Tower with Molten Salt and Heat Storage, and Hybrid Integrated Solar Combined-Cycle (ISCC).
Of course we can't stop eating, playing or living in houses but there are things we can all do to reduce our carbon footprint.
Some of the cuts must come through changing the way people live, particularly in richer nations.
One answer is to combine solar with other technologies, making it one of a mix of possible energy solutions. But an adundance of cheap fossil fuels was already reducing the demand for this technology. Unfortunately, as much as 70 per cent of this heat is lost before it can be put to work by the engine.
