Canada Can be Powered only by Geothermal Energy

- Adam Clare 2 Comments

Geothermal power is yet another proven sustainable source of energy, indeed Iceland’s geothermal production accounts for 99% of their energy production. Researchers in Canada have concluded that there is enough geothermal potential in Canada to power the country solely by geothermal power a million times over!

One of the main advantages of geothermal is that it is available 24 hours, unlike wind and solar, which face intermittency issues.

British Columbia, Alberta, the Yukon and Northwest Territories are the areas where the heat exists closer to the surface, but there are geothermal energy opportunities all over Canada. The researchers estimate that 100 projects would meet the country’s energy needs.

Greenpeace at 40

- Adam Clare

I’ll come out and say that I”m a keen supporter of Greenpeace so I’m happy to point out all the good work they’ve done over the past 40 years that they’ve been around. You can see what Greenpeace actions we’ve covered at Things Are Good in the past.

Greenpeace has put up a slideshow on their site celebrating the accomplishments, you can view it here.

You can read Greenpeace’s blog post on the event here.

From the CBC:

“We wouldn’t see the kind of action by governments that we’ve had in the last 40 years if you hadn’t had that kind of pressure applied by the environmental movement.”

Sept. 15, 1971, is cited as the beginning of Greenpeace, the day a group of anti-nuclear activists in Vancouver called the Don’t Make a Wave Committee chartered a ship with the aim of heading off underground nuclear tests by the U.S. government on the remote Alaskan island of Amchitka. In anticipation of the protest, the vessel, Phyllis Cormack, was renamed Greenpeace, a term coined by activist Bill Darnell.

The ship was ultimately blocked by the U.S. Coast Guard before it could reach Amchitka, and the scheduled tests went ahead as planned. But the protest aroused significant public interest in the group, which was renamed Greenpeace International in 1972.

California Bans Shark Fin Soup

- Adam Clare

There are tons of reason to ban shark fin soup, and it’s not just because it’s cruel to sharks.

“Sharks have been around for nearly 400 million years, and could be wiped out in a single human generation due to an increasing demand for their fins,” said Knights. ”Fisheries regulation on the ground has utterly failed to reduce overfishing — market approaches like this are crucial.”

Fins from up to 73 million sharks per year are used to make shark fin soup, a vastly popular Asian delicacy. Captured at sea and hauled on deck, the sharks are often still alive while their fins are sliced off. Because shark meat is not considered as valuable as shark fin, the maimed animals are tossed overboard to drown or bleed to death. The process is called shark finning, a wasteful and cruel practice still legal in much of the world.

So in this context it is great to see that shark fin soup has been banned in yet another part of the world. Some people are afraid of sharks (I blame Jaws) yet sharks are vital to a healthy and function ocean ecosystem.

Negative Carbon Concrete

- Adam Clare

The most popular construction material on the planet is concrete and it turns out that the way we use it is not environmentally friendly. What if we changed that?

A company has created a great concrete variation that actually beneficial for the environment as it removes excess carbon!

While it functions much like commonly used Portland cement, boasting the same level of performance and the same average cost, Novacem’s concrete mixture uses magnesium silicate instead of calcium carbonates. The slinging of chemistry jargon might make this seem complicated, but the concept is simple: the creation of magnesium carbonates from magnesium silicates absorbs carbon dioxide. In other words, the production process is carbon negative. Furthermore, the production process of Novacem’s concrete is low-energy, allowing it to be sustained on biomass fuels.

Brazil: Wind Power Now Cheaper Than Natural Gas

- Adam Clare 1 Comment

In Brazil a recent energy auction has shown that wind power is cheaper than natural gas in the country, and also a better investment opportunity. The competitiveness of sustainable energy sources continues to impress everyone (even with the subsidized resource-extraction industries), it’s only a matter of time until other sustainable energy options get this cheap.

They even expect the cost of wind power to decrease in the coming years!

EPE president and chief executive Mauricio Tolmasquim said the auctions show that wind and natural gas are competitive, predicting wind prices will continue to fall in Brazil.

“That wind power plants have been contracted at two digit prices, below 100 reals per MWh, showcases the energy market competition through auctions,” he said. “That wind power could reach these lows versus natural gas was unimaginable until recently.”

The energy auctions for a total of 92 projects were the first in Brazil for 2011, and also featured biomass, hydro-electric and natural gas projects.

Investments amounted to 11.2bn reals in total, for 3,962MW of energy that is slated to start generating in 2014.
