World’s solar power won’t save ANY energy until 2020
Worldwide, Daily news | ankakh | April 5, 2013 1:33A new study has claimed the vast construction of solar farms around the globe has used so much fossil fuel they will not contribute any ‘real’ energy to the world until 2020.
TheStanfordUniversitystudy analysed the fossil fuels used in the construction of solar panel.
It found the panels have only just begun to surpass the amount of energy ploughed into created new solar installations.
With continued technological advances, the industry is poised to pay off its debt of energy as early as 2015, and no later than 2020, the report concluded.
Supporters of solar power hope the industry will develop new, easier to produce panels.
‘Developing new technologies with lower energy requirements will allow us to grow the industry at a faster rate,’ said Sally Benson of Stanford’s Global Climate & Energy Project.
To be considered a success – or simply a positive energy technology – PV panels must ultimately pay back all the energy that went into them, said Dale.
The energy payback time can also be reduced by installing PV panels in locations with high quality solar resources, like the desert Southwest in theUnited Statesand theMiddle East, the team believe.
They say many panels are simply installed in the wrong countries.
‘At the moment,Germanymakes up about 40 percent of the installed market, but sunshine inGermanyisn’t that great,’ Dale said.
