A Global Shift to Renewable Energy

Solar-Power Plane Stays Aloft For 26 Hours

Show
BERN, Switzerland, July 8 (UPI) -- A solar-powered plane completed its test flight, staying aloft for 26 hours and 9 minutes before landing near in Bern, Switzerland, its pilot said Thursday. The record-setting feat caps seven years of planning, bringing the Swiss-led project a step closer to its goal of circling the globe using only solar energy, The Daily Mail of London reported. "We achieved more than we wanted.

Emerging Renewables To Have More Profile In Next Statistical Review

Show
The ‘Statistical Review of World Energy’ does not include wind, solar or geothermal in its primary energy forecast, but these sources will be added next year because they are reaching “sufficient weight in a number of countries.”

Hydroelectricity and nuclear remain the largest non-fossil fuels in the world, with a combined share of 12% in primary energy, explains BP’s chief economist Christof Rühl in the 2010 Review. ... Read more about Emerging Renewables To Have More Profile In Next Statistical Review

Earth Policy Release Data Highlights

Concerns about global warming, rising fossil fuel prices, and oil insecurity have prompted calls for a new energy economy, one that replaces fossil fuels with renewables. The sun is an enormous reservoir of energy; in fact, the sunlight reaching Earth in just one hour is enough to power the global economy for a whole year. ...

Renewables Global Status Report 2009 Update

Show

The year 2008 was the best yet for renewables. Even though the global economic downturn affected renewables in many ways starting in late 2008, the year was still one to remember. As Table 1, on page 22, shows, in just one year, the capacity of utility-scale solar photovoltaic (PV) plants (larger than 200 kW) tripled to 3 GW. All forms of grid-tied solar PV grew by 70%. Wind power grew by 29% and solar hot water increased by 15%. Annual ethanol and biodiesel production both expanded by 34%. ... Read more about Renewables Global Status Report 2009 Update

How Much Surface Area Would It Take to Power the World Completely With Solar or Wind?

Show

Ever wonder how much space we would need to use to power the entire world with solar energy or offshore wind power? So did the good people at the Land Art Generator, who created two infographics that show the amount of surface area required to power our planet with renewable resources. According to Land Art Generator, 496,905 square kilometers are needed to power the world with solar energy. That's less than the surface area of Spain. And just a piece of the Sahara Desert could power all of Europe and North Africa. ... Read more about How Much Surface Area Would It Take to Power the World Completely With Solar or Wind?

Where should new solar and wind power facilities go? Seems many of the best potential sites, including rugged, windswept regions in the Rocky Mountains to the sun-baked Mojave Desert, contain swathes of land legally set aside as national parks, or support what remains of an endangered species' dwindling habitat, for example. ...
