Last year was the first time that investments in renewable energy exceeded those in fossil fuels, according to Bloomberg New Energy Finance.
Even in a recessed economy, investments in wind and solar power hit $187 billion last year, compared to the $157 billion that was funneled into natural gas, oil and coal.
What accounts for this switch? Renewable energy subsidies have increased, for one thing. Last year, they exceeded $66 billion. People also seem more willing to look into solar and wind energy -- perhaps especially because of the recession.
As even more new energy innovations emerge, it will be fascinating to see how society reacts.
