Solar collector

A solar collector allows energy collection in a square. Sea level solar collectors will collect 1 energy per turn. Solar collectors at higher altitudes will collect an additional energy for each 1000m above sea level.

Background
Before the development of cheap fusion power, most colonial bases were powered by solar-power or windmill farms. Solar cells, tilted to catch the sun as efficiently as possible, covered acres of landscape. Other regions, enjoying consistently strong winds, saw the construction of vast windmill farms. Both techniques were usually applied at high elevations, where winds were more consistent and cloud cover was less likely to interfere.
