Colonization of the outer Solar System Colonization of the outer Solar System Many parts of the outer Solar System have been considered for possible future colonization. Most of the larger moons of the outer planets contain water ice, liquid water, and organic compounds that might be useful for sustaining human life. Colonies in the outer Solar System could also serve as centers for long-term investigation of the planet and the other moons. In particular, robotic devices could be controlled by humans without the very long time delays incurred in communicating with Earth. There have also been proposals to place robotic aerostats in the upper atmospheres of
Solar power in Maryland of S.B. 791, solar hot water systems. Solar hot water systems have a 5 SREC limit. The passage of H.B. 1187, also on May 22, 2012, accelerates the state's Renewable Energy Portfolio Standard with a target of 20% by 2020, of which 2% must be solar. Currently, there is no limit on the system size for a photovoltaic system. In the state of Maryland, one SREC is equal to one MWh of electricity production, and is redeemable for three years. As of January 2017, an SREC is valued at $18, and if the RPS is not increased is expected to
