New green idea builds solar-powered greenhouses on fallow land

New green idea builds solar-powered greenhouses on fallow land

Noting that there are around 200,000 hectares of fallow land around Taiwan, the Environmental Protection Administration (EPA) minister suggested yesterday that building "photonics greenhouses" on such land as part of efforts to promote the development of renewable energy would be a good policy.
Such facilities can not only use solar energy to generate power but can also be used to raise valuable cash crops such as orchids, said Stephen Shu-hung Shen in an interview with CNA.
Shen said photonics greenhouses use photonic technology in which light- pervious thin-film solar cell panels are installed on the roofs of the facilities.
These cells are capable of separating blue-green light from the red-orange part of the spectrum and using it to generate power, while taking advantage of the heat emitted from the red-orange rays to warm the greenhouses, Shen said.
If all the fallow land around the country could be used to house such greenhouses, they could not only provide generous power to neighboring areas but could also serve to raise crops with high economic value, he added.
The minister also disclosed that the EPA is in contact with the German government, which is experienced in the development of renewable energy, and is seeking its assistance in sending experts and scholars to Taiwan to share their knowledge and experience in the field.
The EPA is also hoping to host a forum in Taipei in April with the participation of those foreign experts, Shen added.
