BBC - Future - How China's giant solar farms are transforming world energy
forrás
"Liu points out that solar panels continue to get cheaper and cheaper. As such, it may only be a few years before China’s slashed subsidies become irrelevant – solar energy will just be too deliciously inexpensive for investors to ignore. It will be between three and five years before solar is cheap enough to build confidently without subsidy, she says.
But should giant solar parks continue to be built, one oft-ignored complication will have to be dealt with in future decades: solar panel waste. The panels last just 30 years or so, after which they must be broken up. It is hard to recycle them because they contain harmful chemicals like sulphuric acid. China is expected to experience a sudden boom in solar panel waste from around 2040 onwards and there is currently no clear plan for what to do with all that material.
Not quite as problematic as nuclear waste, perhaps, but it is one more hurdle to overcome when ensuring that large-scale solar energy really is a ‘green’ technology."
Egyre "olcsóbb-olcsóbb", de az újrahasznosítást meg kell oldani, (ami viszont nem lesz ingyen), mert különben oda a nagy "zöldség".
