There are roughly 600 million people in sub-Saharan Africa who currently live without electric power. Putting in the infrastructure to supply power to these people in their various countries has been a major economic and logistical challenge.
It is increasingly clear that the rate at which carbon dioxide emissions are being reduced is not sufficient to prevent dire consequences of climate change. It appears that it will be necessary to try to actually remove carbon dioxide from the air. Such actions are termed “negative emissions.”
Electric buses are replacing conventional diesel-fueled buses at an accelerating rate that is outpacing the adoption of battery-powered cars. According to forecasts by Bloomberg New Energy Finance, by 2030 some 28% of car sales will be electric vehicles while 84% of new buses will be electric buses. So far, some 12 years away, the actual adoption of electric buses is outpacing this optimistic projection.
Los Angeles has a tremendous thirst for electric power and is always trying to find new sources. On December 1, the Los Angeles Department of Water and Power began buying all the power generated by the brand-new 24 MW Tungsten Mountain geothermal power plant located in Churchill County in Nevada’s Great Basin region.
UPS recently announced a demonstration project that will put a prototype electric truck powered by a hydrogen fuel cell through the delivery company’s challenging paces. Fuel cells have been used in some commercial vehicles to power auxiliary systems, but this is the first time that they will be used to propel a vehicle.
So far, it has been a big year for the U.S. wind industry, which experienced its fastest first-quarter growth since 2009. In total, about 2,000 megawatts of new capacity was installed, enough to power about 500,000 homes. With this addition, wind now produces 5 1/2% of the country’s electricity.
A South African court recently overturned a national ban on the trade of rhinoceros horns – a decision that was celebrated by the country’s commercial rhino breeders but slammed by animal preservation groups. A moratorium on rhino horn trade had been in effect in South Africa since 2009.
The worldwide decline in the population of bees and other pollinators has impelled farmers to do what they can to encourage and nurture bees on their land. Protecting bees is important because pollinators are essential for growing many foods including coffee, cacao, almonds and many other fruits and vegetables.
Several major automakers are betting on hydrogen-powered cars as the future of personal transportation. The first of these cars are already available in California. What isn’t readily available is the hydrogen to power them. There are very few hydrogen stations out there and hydrogen is pretty expensive.
According to a report from the International Food Policy Research Institute, more than half the world’s population will be at risk of water shortages by 2050 if current trends continue. As the climate continues to change, severe droughts are becoming increasingly commonplace.
The Scottish government has an ambitious plan to meet 100 percent of its demand for electricity from renewable sources by 2020. Like much of the world, Scotland has produced significant amounts of its electricity by burning coal for more than 100 years. But no longer.
In the Northeast, many are enjoying the last of autumn’s bounty. When we grow fruits and vegetables, we can choose to forgo pesticides, GMOs, or industrial fertilizer. When we shop at farmer’s markets, we support family farms and help maintain open space that we all enjoy.
