The jury is still out on solar thermal, which is certainly efficient but has its critics because of its costs, both financial and ecological. The International Energy Association (IEA) is still bullish about its future, and projects such as the Solana Generating Station in Arizona show potential. Large projects such as Masdar’s Shams 1 and California’s Ivanpah have scored plenty of attention, but the rapidly decreasing price of solar panels has made PV more attractive for large projects. But solar thermal technology could have promise for agriculture. At a time when many are pondering how we are going to feed nine billion people by 2050, new projects underway are leveraging solar thermal desalination technology to cleanse water and grow crops in water-stressed regions. Sundrop Farms, based in Port Augusta, Australia, believes it has a solution. The company claims it is the only such company in the world that can build and operate greenhouses in areas that severely lack fresh water, arable land, or access to the electrical grid.
