Australia Can Make Easy Transition to Renewable Energy

- Adam Clare

Presently, 10% of Australia’s electricity is produced from a renewable resource, and that number can grow easily with minor adjustments to federal policy. By cutting back subsidies for the oil and gas sector (yes, most developed nations actually provide subsidies to that insanely profitable sector) and upping the cost of carbon the Australian economy can make an easy transition to more renewable energy. To top it all off, the country is looking at a feasibility study of 100% renewable energy use by 2030!

The researchers found currently available renewable energy technologies such as wind and concentrated solar thermal power could displace all fossil-fuelled power plants in the National Electricity Market, according to a peer-reviewed paper published in the international Energy Policy journal.
…
Running simulations based on power demand and supply data for 2010, the researchers found wind would contribute most in a switch to fully renewable energy. It would account for between 46 and 59 per cent, while solar PV and concentrated solar would supply 15-20 per cent each, and hydro and biofuel-based gas generators the remainder.

Burning in the Sun: The Small Solar Industry in Africa

- Adam Clare

A few years ago in Mali some filmmakers went to chronicle what’s going on in the country and ended up making a documentary about solar energy. Daniel Dembele is an entrepreneur who brought solar power to the people by starting a company and bringing photovoltaic panels to rural Mali. This looks like a good doc!

Founding a small business is something that is deeply embedded in American and European culture. But most have never seen this universal kind of effort take place in Africa, traditionally portrayed by mainstream media as a land of the starving and war ravaged. In our portrayal of Daniel, who undertakes a familiar effort in an unfamiliar environment, we attempt to open the door to on what is viewed as possible in Africa, and update Western cultural awareness with a profound dose of optimism. Daniel’s work shatters notions of the need for African dependence on outside aid and embraces the view that ultimately it is Africans who will develop Africa in their own way.

Now more than ever, people around the world see green-collar jobs as a necessity for survival in our rapidly changing economies and environments. Daniel’s daring, charisma and intelligence remind us of the leadership required to encourage this level of transformative change, anywhere in the world. We showcased Daniel as an African leader, as well as a global trendsetter. We think this allows viewers to understand the kind of micro business development that makes sense for Africa, while also hopefully stirring a profound inspiration to take action in their own communities.

Canada Can Easily Have a Low Carbon Economy

- Adam Clare 1 Comment

Even though Canada has the tar sands it is still possible for the Canadian economy to lower it’s carbon output. According to some recent research into the matter by The David Suzuki Foundation, Canada can compete better with existing low-carbon economies by focusing on being more environmentally friendly and using alternative energy solutions to the tar sands.

In Low-Carbon Energy Futures: A Review of National Scenarios, the TEFP summarizes common themes in leading greenhouse gas reduction strategies for eight countries: Australia, Canada, Finland, France, Germany, Sweden, the United Kingdom and the United States. The study shows that:

  • Canada and other industrialized countries have the technology to achieve an 80 per cent reduction in their energy-related greenhouse gas emissions by 2050.
  • The transition to a low-carbon energy future will be transformative, requiring a boom in clean-energy technologies and low-energy practices at least as significant as the post-Second World War boom in fossil fuel consumption.
  • Per capita fuel and electricity consumption is about twice as high in Canada, the U.S. and Australia as it is in France, Germany, Sweden and the U.K. Yet even those countries produced scenarios that targeted 80 per cent reductions in their remaining GHG emissions by 2050.

LED Street Lights Save Los Angeles Millions

- Adam Clare

Four years ago Los Angeles decided to change its street lighting to LEDs and the results have come in and the savings are phenomenal. They have converted a little over half of all their street lights and are already saving $5,325,793 annually in lighting costs. It’s worth noting that LEDs use 80% less electricity than traditional lighting solutions while also providing better lighting for users of the street.

Hopefully the success that LA has seen will encourage other cities to make the switch to cheaper and more efficient lighting.

Maintenance savings are real, too: In 2008, pre-LED roll-out, Los Angeles logged 70,000 street light repair and maintenance events; in FY 2012, maintenance and repair events fell to 46,300. LEDs are longer lived than the incumbent units they replace (10-15 years versus 4-6 years), which means that maintenance should steadily decline as LED units are fully deployed. A remote monitoring system, installed with the LED fixtures, indentifies problems in real time.

LED fixtures also fail at a lesser rate than incumbent technologies. After 36 months of initial operation, for instance, high-intensity discharge (HID) fixtures in Los Angeles recorded an average failure rate of 10%; the average failure rate for LED fixtures, according to the latest figures, is 0.2% (189 of 98,000 installed). At full LED deployment, Los Angeles expects to save $2.5 million annually on maintenance costs.

France Wants Lights to be Turned Off

- Adam Clare

France has passed a law that will make it illegal to keep lights turned on over night in non-residental buildings. Starting in July the lights need to be out an hour after the last employee leaves. This is a great way to save energy while reducing light pollution.

The move, announced on Wednesday, is expected to save 250,000 tonnes of CO2 – enough energy to power 750,000 French households for a year.

The French ecology minister, Delphine Batho, said she hoped the law would change attitudes in France and help the country become a pioneer in reducing light pollution.
