Pacific Island 100% Solar Powered

- Adam Clare

Tokelau is a small island in the Pacific that has switched it’s entire power grid to solar, this is the first of a few islands in the region that will be fully independent from having to import fuel for electricity.

Before the solar power grid was completed, the New Zealand-administered grouping of three coral atolls, with a population of just 1,500, relied on diesel generators for electricity. Project coordinator Mike Bassett-Smith said the diesel was not only environmentally unfriendly, it also cost the islands, which lie about halfway between New Zealand and Hawaii, around NZ$1.0 million ($825,000) a year.

Bassett-Smith, from New Zealand firm PowerSmart Solar, said the change would allow Tokelau to switch money from fuel purchases to social welfare projects.

“For Tokelau, this milestone is of huge importance for their continued well-being,” he said in a statement received Wednesday.

Solar Panels Break 1/3 Record

- Adam Clare

Photovoltaic solar panels are measured in terms of how efficient they are at converting light into electricity. Obviously potential energy is lost when this conversion occurs and it has long been speculated that it would be possible to get 1/3 of the energy captured converted into electricity. In labs, this is a relatively easy task, however doing this in the field proves to be rather hard.

An American company announced recently that they have been able to achieve this level of efficiency on a regular enough basis.

During a period of testing by the National Renewable Energy Laboratory back in May, a peak efficiency of 34.2 percent was achieved, which Amonix claims is the highest ever reached by a PV module under real-world conditions. However, Amonix is only now drawing attention to the breakthrough, which saw its own record of 30.3 percent efficiency broken.
…
The solar module efficiency is the efficiency of the panel, and not the same as the efficiency of individual solar cells from which it’s comprised. At the moment, solar cell efficiency can just exceed 43 percent for concentrated systems. It’s the module efficiency, however, which reflects the amount of electricity a PV system can produce.

Saudi Arabia Plans for 100% Renewable Energy

- Adam Clare

67 year old Prince Turki Al Faisal Al Saud wants Saudi Arabia to be fully powered by renewable energy in his lifetime. Saudi Arabia is one of the largest oil producers in the world and is probably the most symbolic oil-rich nation. The fact that the country’s leaders want to transition away from oil despite the fact that they are oil rich highlights the need to stop relying on finite fossil fuels.

If Saudi Arabia can transition to renewable energy than the rest of the world can surely do it too.

However, he insisted Saudi was moving ahead with investment in renewable energy, nuclear power and other alternatives to fossil fuels and that it could use its vast oil reserves for other goods, such as plastics and polymers.

“Oil is more precious for us underground than as a fuel source,” he said. “If we can get to the point where we can replace fossil fuels and use oil to produce other products that are useful, that would be very good for the world. I wish that may be in my lifetime, but I don’t think it will be.”

Joss Garman, political director of Greenpeace, said: “It speaks volumes that a Saudi prince can see the benefits of switching to clean energy sources when [UK chancellor] George Osborne seemingly cannot, but Saudi Arabia will only truly be a green economy when it leaves its fossil fuels in the ground.”

Tesla Motors Builds Solar Charging Stations

- Adam Clare

Tesla, the electric car company, has unveiled solar powered electric charging stations in the USA. This is a good step toward sustainable personal transportation.

Not only has Tesla created battery charging stations called Superchargers for electric cars but they are giving the energy away for free to some lucky people. If you own a Model S car made by Tesla then you will soon be able to travel for free right across the USA.

The six California locations unveiled today are just the beginning. By next year, we plan to install Superchargers in high traffic corridors across the continental United States, enabling fast, purely electric travel from Vancouver to San Diego, Miami to Montreal and Los Angeles to New York. Tesla will also begin installing Superchargers in Europe and Asia in the second half of 2013.

The Supercharger is substantially more powerful than any charging technology to date, providing almost 100 kilowatts of power to the Model S, with the potential to go as high as 120 kilowatts in the future. This can replenish three hours of driving at 60 mph in about half an hour, which is the convenience inflection point for travelers at a highway rest stop. Most people who begin a road trip at 9:00 a.m. would normally stop by noon to have lunch, refresh and pick up a coffee or soda for the road, all of which takes about 30 minutes.

Typical Wind Farm Supports Nearly 1,100 Jobs

- Adam Clare

A recent report by the Natural Resources Defense Council (NRDC) in the USA has shown that in the country wind farms generate not just energy but 1,000 jobs at a ‘typical’ site. Other countries have found that incorporating renewable energy into their electricity grid can help generate power efficiently while helping to revitalize areas that have not found economic success in the modern world.

A new 250-megawatt wind farm will create 1,079 jobs throughout the many steps of building that wind farm, according to the NRDC report “American Wind Farms: Breaking Down the Benefits from Planning to Production.” These are positions in manufacturing, construction engineering and management, among other areas.

But the benefits don’t end there, a separate NRDC study on the secondary impacts of the wind energy industry shows.

Wind farms also are helping revitalize communities across the country by generating new taxes, lease payments to landowners and economic development revenues, in addition to creating new job opportunities, the NRDC report “At Wind Speed: How the U.S. Wind Industry is Rapidly Growing Our Local Economies,” shows. The report profiles four communities from Ohio to Oregon that have benefitted from the wind industry.
