Four Underused Alternative Energy Sources

Alternative energy is commonly defined as any type of energy source other than traditional fossil fuels. More than ever people are looking for alternative energy sources as the costs of traditional fossil fuels rise and the environmental impacts of their use become clearer. Biofuels, wind power, hydrogen and geothermal are some of the more popular alternative energy choices, but they are still much underused.ALTERNATIVE BIOFUELSBiofuels, like fossil fuels, are generated by taking organic matter and then converting it into some form of combustible fuel. Biofuels, however come from much more recent sources. The term biofuel covers ethanol and other such derivatives from sugar cane, corn and other vegetable oils. Many have hopped on the biofuel bandwagon for the simple reason that they are considered a renewable resource, and unlike fossil fuels, will be able to be produced as long as plants continue to grow. Admiration for biofuels is not universal, however. Some see the potential food sources we are converting into fuels and feel they would be put to better use feeding the poor and malnourished. Others also feel that they are no real alternative to traditional fuels, as they produce many of the same pollutants.WIND POWERWind power is electricity created when wind turns a turbine to produce electricity. Another of the more popular alternative energies, wind power comes with some drawbacks as well. First is the unreliable nature of the wind. Second, near coastlines and many other places where there is an almost constant breeze, locals have fought tooth and nail to stop proposed wind farms. One reason given for opposing such construction is aesthetics. Some people think they will ruin their property values or stick out like a sore thumb in otherwise pristine views, although advances in technology are working toward making smaller less obtrusive wind turbines.HYDROGENHydrogen power has been proposed as a direct replacement for gasoline for quite some time. However, there are several reasons why it has never achieved prominence, even though companies such as GM and Ford have gone as far as producing prototypes. First, Hydrogen is still expensive to produce, although it is getting cheaper. Secondly there are worries about transporting and storing it, as it can make some metal tanks and pipes more brittle and prone to leakage. GEOTHERMALGeothermal power has been in use for quite some time, and is quite efficient, but has up until recently been limited in scope to plate tectonic boundaries. Newer computerized control technologies like the ones produced by Greensleeves Energy Solutions are helping to make geothermal units smaller, more efficient, and able to be placed in more diverse locations. Greensleeves focuses on reducing energy in an affordable manner for commercial buildings.Biofuels, wind, hydrogen and geothermal energy are some of the more popular but underutilized alternative fuels. However, technological advances are allowing them to compete with fossil fuels more and more.Follow Dude, Sustainable! on Twitter or Pinterest, or subscribe to our newsletter.

Fukushima Japan Accelerating Deployment Of Solar To Create Self Reliant Communities

San Diego, Calif. - This March will mark the four-year anniversary of when the world's worst nuclear disaster since Chernobyl hit the northeast of Japan. Communities severely affected by the triple-disaster of earthquake, tsunami and nuclear meltdown have made a strong commitment to become energy self-reliant by producing safe, clean energy locally for local consumption. View of Iitate Village, Fukushima Prefecture The entire village of litate, located at 39 kilometers northwest of the Fukushima Daiichi Nuclear Power Plant, was forced to evacuate in order to avoid radiation exposure. To build a self-reliant community, a few of the villagers from litate got together to establish the litate Electric Power Company. litate is building a 50-kW solar system, and upon completion of the system in February, it will sell the power output to local utility Tohoku Electric Power Co....

U S Should Learn From This India Coal Tax Has Collected 2 85 Billion

What a great way to raise capital to invest in more secure infrastructure for the country of India. Just think, even a small tax on fossil fuels to pay for the infrastructure needed to grow renewable energy would be astronomical. One of the greatest cost of new renewable energy installation is new infrastructure needed to transfer that power to where it is needed. With the low price that renewables now enjoys the economics would be beneficial to both the generators and the consumer. We have a energy infrastructure that is already at capacity and in many places at the end of use life. This country needs a new energy infrastructure in the worse way even without new generation methods. If one were to take just the calculated cost the fossil fuel economies impact on the environment and apply that to new infrastructure it would pay for itself many times over.

Smiti Mittal

India has managed to generate 2.85 billion in revenue from clean energy cess (taxes) it had introduced in 2010, essentially a coal tax.India's plans to significantly boost renewable energy infrastructure over the next few years has got a shot in the arm as the government recently announced that it has about 2.85 billion in the National Clean Energy Fund. The fund is replenished by a tax on every tonne of coal mined or imported into the country. Since its introduction in 2010, the tax was 50 per tonne for four years, but the new government doubled this tax in its first union budget announcement earlier this year.The National Clean Energy Fund will be used tofinance solar power projects under theNational Solar Mission and set up dedicated transmission lines for renewable energy projects across the country. The funds may also be disbursed to government bodies like the Indian Renewable Energy Development Agency (IREDA), which will further grant loans to renewable energy projects at concessional rates.

The government is also expected to provide viability gap funding to ultra mega solar power projects currently being pursued by various public sector companies and the recently announced canal-top solar power program from the National Clean Energy Fund.India plans to add 100 GW solar power capacity by 2022, an increase by five times over its initial plan announced in 2010. This plan would require a total investment of about 100 billion. Thus, foreign financial assistance in significant amount will be needed in addition to government-led investment. Such international funds have also begun to flow with the World Bank recently announcing debt financing for a 750 MW solar power project.

Heres How The Large Scale Ret Can Be Easily Met

The next time you talk to a politician or a journalist like Judith Sloan and they say "we need to scrap the RET is because the large scale target can't be met and that will drive electricity prices up" tell them to get stuffed and catch up on reality. Here is just one project, with more than 2GW of potential that is well developed and ready to go to the next stage. And it can be done in around a hundredth of the time of a coal fired plant of a brazillionth of the time of a nuclear plant and requires less subsidies.

Story by Giles Parkinson, RENEWECONOMY.

A staged plan to build what would be the largest solar PV plant in Australia - and possibly the largest yet proposed in the world - has been granted planning approval in Queensland.

Solar Choice, which manages commercial solar power tenders and has been working on building a pipeline of major solar projects, has been working on the Bulli Creek Solar Farm in southern Queensland, a few kilometres from Powerlink's 330kV substation near Millmerran, for the past 18 months.

On Monday, the Bulli Creek project received approval from the Toowoomba Regional Council for a total footprint of up to 2 gigawatts (2,000MW) over the next eight years across 13,000 acres of cleared, flat cattle grazing land. It has the option of building out the site in manageable stages of 100MW to 500MW or more per stage.

The connection process for an initial 550MW is underway with Powerlink. Preliminary studies from transmission engineers Digsilent indicate a total potential capacity at the Bulli Creek substation of well over 1GW, and perhaps over 2GW.

The uncertainty of Australia's clean energy policy still presents a significant hurdle, but Solar Choice says the Bulli Creek project is attracting attention from a range of global investors prepared to take a medium- and long-term view.

It remains open to a large-scale investor, willing to move ahead of competitors by adding a "pipeline ready" project to their portfolio.

Managing Director of Solar Choice, Angus Gemmell, says the Bulli Creek Solar Farm is one of a very small and select number of mega-scale solar projects that Solar Choice has strategically located at transmission nodes on broad-acre lands with high solar irradiation, west of the Great Dividing Range.

These include a 1GW solar project currently being progressed through the Whitsundays Regional Council, directly adjoining Powerlink's 275kV Strathmore Substation at Collinsville. Another 300MW project, the Gannawarra Solar Farm in north-western Victoria, is already planning approved on the 220kV transmission lines between Swan Hill and Kerang.

"We believe that large-scale solar is on the right side of history - it's not a matter of if these projects will be built, but when," Gemmell told RenewEconomy in an interview.

That will not be anytime soon, unless the federal government recommits to the Renewable Energy Target. Its attempts to cut or abolish the target has brought investment in large-scale wind - and emerging solar projects - to a complete halt, apart from companies such as Solar Choice that are prepared to go up-stream and take on development risk towards "pipeline ready" status.

A lot of the Coalition's problems with the RET appear to be built around its distaste of wind farms. But many, including Bloomberg New Energy Finance, suggest that large-scale solar projects will account for up to half of the approx 8GW of new projects required to meet Australia's current 41,000GWh target.

That's because solar costs are falling faster than wind energy costs, and their daytime production means that, in theory at least, their output is more valuable for peak pricing on the National Electricity Market.

However, recent pricing trends that show falls in the midday hours - courtesy of rooftop solar - may challenge those assumptions or perhaps just make the use of trackers for large-scale PV projects more appealing to access the morning and afternoon peaks. Horizontal single axis trackers are now a matter of course for many 100MW plus projects globally.

Still, Gemmell says a few very large-scale solar projects would perhaps enjoy more public support in regional Australia than wind energy. Just a few of those projects could meet one-third or more of new capacity requirements under the current RET.

Gemmell says that the Bulli Creek Solar Farm would be unlikely to start construction before 2016, but building it incrementally in modular stages would allow for storage to be added as the costs of that technology came down. Council's planning approval allows for numerous battery storage warehouses across the site in due course.

"Once the first one or two stages are in the ground, subsequent stages will be all the more bankable," he says.

Despite Australia having the longest contiguous grid in the world, vast space, modern infrastructure and one of the best solar resources globally, it has only a handful of large-scale solar projects currently under construction, including the 102MW Nyngan and 53MW Broken Hill projects, and the 57MW Moree solar project (with tracking). But all three have been heavily dependent on government grants.

One smaller 20MW project at Royalla in the ACT has been built with the help of 25-year power purchase agreements auctioned under the ACT government's ground-breaking reverse auction tenders. Two others have been awarded as part of the ACT's plan to source 90 per cent of its electricity needs from renewable energy by 2020. Additionally Solar Choice has its own 2.3MW Mount Majura Solar Farm in ACT that is moving into construction this year.

Gemmell says there are three avenues to market - the traditional PPA route with large energy retailers - which would likely only happen with a binding RET or once aging coal generators are eventually taken off-line.

The second option is a "pass-through" PPA, which is one that is designed to match the generation capacity with the demand needs of a bankable customer, or customers, most likely large industrial or manufacturing loads.

The third option - though one that is likely some way into the future, and dependent on getting costs down to the levels of the US and Middle East where solar plants cost less than 100/MWh - is to sell the output into the wholesale market. This is already happening in Chile.

If the January 2015 award in Dubai of a 260MW PV project at US 0.0585c per kWh is any yardstick, the latter prospect may not be so far away as many think.

How Geothermal Energy Works

More people are talking today about how to save fuel and how to find more energy efficient ways to do the things we need to do every day. Geothermal heat and energy are one revolutionary way to use the natural energy that's in the earth to power our homes and buildings. In addition to being more energy efficient, geothermal heat helps reduce global warming and helps contribute to the goal of geothermal exchange.

If you're thinking about using geothermal energy for yourself, then it's important to know how it works so you can know for sure if it's right for you. The easiest way to explain is that geothermal heating works with the use of pumps. Underneath the frost line of the earth's surface, the ground will always stay at a certain temperature. This is usually right around 57 degrees. This is a good temperature for the heat pumps. The geothermal heating works by circulating the water in an underground loop through this natural part of the earth. The loop is called a heat exchanger. Next it is transported through water to air heat pumps that have located in the building and the heated air is pumped out to warm the rooms.

For this heat exchanger to work it is buried about 150-300 feet into the earth's surface. It is made from a high density polyethylene type of pipe which can withstand the temperatures and the conditions underground. The constant temperature of the earth will help balance the temperature of the air that is being cycled through.

Heat and cool air is pumped in and out of the home and through the geothermal piping as needed to keep your home or building at the temperature you desire. This is a very safe and natural way to control the heating and cooling in your home or office building. Geothermal methods can be used no matter how small or large the building.

Other benefits to a geothermal heating and cooling system is that they are easy to use. Many people assume since it is a new thing that it will be complicated or difficult to use but this is not the case. Buildings that choose to use it will not need a boiler operator or chiller technician and any building or home that uses it can save from 25-40% on their energy efficiency.

Over the years that geothermal has been in use and tested, the design of the geothermal systems has been improved upon more and more. It continues to advance over time and as more people become aware of it and begin to use it, too. This helps our environment and can help you save a lot of money on your heating and cooling bills.

Now that you understand more about how geothermal heating and cooling works, you can see why it could be a great choice for you if you want to save on electric bills while helping your environment at the same time.
