Using Giant Floating Turbines in the Future

- Adam Clare

Last year we looked at a company testing floating wind turbines in Alaska and how they want to use these turbines in remote locations. The testing seems to be going well and other companies have taken note. The amount of potential energy high in the atmosphere is massive and these floating turbines are well suited to capture that energy.

Over at Gizmodo they looked into the future of how these wind turbines can be used and their potential for transforming how we produce energy.

This is all to say that we use a lot of power, and could probably harness a lot more of it using wind turbines. Which brings us back to the question we started with: What if we changed the climate with wind turbines? I know this sounds totally crazy, but I swear to you this is something that scientists have actually looked into. So naturally, I talked to one of those scientists.

Community Solar Garden to Open in BC

- Adam Clare

Germany, and to a lesser extent other nations, have championed community-owned sustainable energy production. In many ways it gives power to the people. Indeed, one way to encourage mass adoption of sustainable energy is to make policies which favour decentralized and community owned production. This means that big utility companies often oppose such efforts.

In British Columbia the city of Nelson may be the first city in Canada to take on this German-insipred approach. They are looking to open a solar facility which not only provides energy to the people it provides added revenue.

A community solar garden is a centralized solar panel farm that gives homeowners and businesses access to solar energy without having to install and maintain panels on their own roof.

The price of the electricity purchased from the proposed solar project in Nelson would cost residents more, but initial community feedback indicates people would be willing to pay the extra costs, said Proctor.

It’s about more than trying to save money, she said, and added costs eventually will even out.

Nelson Hydro is still working out detailed costs, but says people could end up investing something like $1,000 for a solar panel space for 25 years. They can either pay a lump sum up front or make monthly payments of about $3.47 until the solar panel space is paid off.

Marine Life Drawn to Offshore Wind Farms

- Adam Clare

Renewable and sustainable energy is pretty great on its own. Now there’s one more reason to support using wind as a energy source because when the wind turbines are placed offshore marine wildlife moves in. The world’s oceans are suffering from overfishing and other human caused carnage so providing marine animals with shelter is something we should be doing.

The fact that wind turbines can provide sustainable energy while helping marine animals survive is good news indeed.

Offshore wind farms can be fertile feeding grounds for seals who choose to seek them out – concludes the study, by an international team of researchers from Britain, Holland and the US, published yesterday in Current Biology Journal.

This is because the presence of a hard structure beneath the waves attracts barnacles and other crustaceans, and, in turn, fish. Dr Deborah Russell, a research fellow at the Scottish Oceans Institute at the University of St Andrews, explained how the “reef effect” attracts seals. “Things like barnacles and mussels will settle on hard structures and then that in turn will attract other marine species and it builds up over time.”

Global Solar and Wind Energy Production Continues to Grow

- Adam Clare 1 Comment

The sustainable energy market consistently needs to prove its worth despite the obvious benefits, whats worse is that the industry as a whole is up against the subsidized fossil fuel industry. Despite the artificially lowered fossil fuel prices sustainable energy solutions continue to prove their economic worth.

Global solar and wind energy capacities continued to grow even though new investments in these energy sources declined during 2012. Global investment in solar energy in 2012 was $140.4 billion, an 11 percent decline from 2011, and wind investment was down 10 percent, to $80.3 billion.But due to lower costs for both technologies, total installed capacities grew sharply.

Solar photovoltaic (PV) installed capacity grew by 41 percent in 2012, reaching 100 gigawatts (GW). Over the past five years alone, installed PV capacity grew by 900 percent from 10 GW in 2007. The countries with the most installed PV capacity today are Germany (32.4 GW), Italy (16.4 GW), the United States (7.2 GW), and China (7.0 GW).

Europe remains dominant in solar, accounting for 76 percent of global solar power use in 2012. Germany alone accounted for 30 percent of the world’s solar power consumption, and Italy added the third most capacity of any country in 2012 (3.4 GW). Spain added the most concentrating solar thermal power capacity (950 MW) in 2012 as well. However, Italy reached the subsidy cap for its feed-in tariff (FIT) program in June 2013 while Spain recently made a retroactive change in its FIT policies, meaning growth in solar energy will likely slow in these countries in the near future.

Mongolia Builds Their First Wind Farm

Mongolia is entering the sustainable energy market and the country aims to export renewable energy to its neighbours. It’s great to see countries that are not as well-off as others build the needed infrastructure for a sustainable future.

Mongolia is so windy and has such harsh winters, in fact, that the turbines at Salkhit were built specifically to be “Mongolia-proof” so they could survive the strong winds and winter freeze. Each blade is ~120 feet and the tower and blade combined are 384 ft. However, because Mongolia’s roads are still so bad, the turbines had to be transported directly over the steppe! It took three months for the pieces to arrive from China, where they were manufactured.
…
This project is still just one of what will need to be many wind and solar power projects in order for Mongolia to realize its vision of becoming a net exporter of energy to neighbors in China and Russia. Every journey has a beginning, and it was great to see Mongolia taking this important first step.
