Is all this effort to save energy worth it?
Consider this. Had we neglected energy efficiency from 1980 to 2010, worldwide energy use would be 35 percent higher. What does this mean? Look at the amount of energy used in the world’s two largest economies – the United States and China. That’s about how much energy the world saved. (more…)
A new report compiled by Greenpeace International and the Global Wind Energy Council on the future of the wind industry and released yesterday in Beijing says wind power could supply up to 12 percent of global electricity by 2020, creating 1.4 million new jobs and reducing CO2 emissions by more than 1.5 billion tons per year, more than 5 times today’s level. By 2030, (more…)
While renewable energy sources still provide a small portion of the world’s power needs, several new reports suggest that the global community may be underestimating the growth potential for the green energy sector.
Global carbon dioxide emissions reached record levels in 2011, driven largely by a 9.3-percent increase in Chinese emissions, according to a new report by the International Energy Agency (IEA). According to preliminary estimates, worldwide carbon emissions climbed to 31.6 gigatonnes in 2011, a 3.2-percent increase from 2010. (more…)
Heavy sigh. I just read an article that dampened my day – and that’s saying something considering the rainy Vancouver weather we’ve been experiencing this spring. I read that the carbon dioxide emitted by energy use hit a record high globally in 2010. After a slight dip caused by the global financial crisis in (more…)
It’s a commonly held perception that Europe leads the Western world with respect to energy efficiency. In many ways, it’s true. Europeans tend to live in smaller homes than Americans and are less fond of air conditioning and other energy-intensive equipment and appliances. The Passivhaus standard, which has (more…)
It’s been Halloween time here in the U.S., and the ghosts and goblins haunting my neighborhood (and trolling for candy) got me thinking about how there are things out there that are beyond the comprehension of most of us. Often, the solutions to difficult problems fit into that category. In (more…)
