Sitting on the southern edge of the Arabian peninsula, Oman is rich in fossil fuels -- particularly natural gas, some 11.73 trillion cubic feet of it.
It might, then, come as a surprise to see greenhouses popping up in the country's deserts.
GlassPoint Solar is a company looking to harness Oman's abundant renewable energy - sunshine - to actually help the country produce more oil in a process called enhanced oil recovery, or EOR.
"The way the system works is that giant mirrors focus sunlight on to a pipe containing water," Rod MacGregor, President and CEO of GlassPoint Solar, told CNBC's Sustainable Energy.
"The heat from the concentrating sunlight boils the water to produce steam, (and) that steam can then be injected into an oil well," MacGregor added.
