Power generation, renewable forms

Johansson et al. projected aggressive scenarios for a renewable energy-intensive economy in which 40 percent of direct fuel use (for everything except power generation) comes from renewables, mostly in the form of biomass, by 2050. Direct use of biofuels exceeds direct use of oil in their scenario.59... 

An OTEC installation comprises a power generating subsystem subsystems to convert the electric powerproduced to forms useful for power transmission and fuel production energy storage and transfer equipment equipment for position control of floating systems and facilities (ships, platforms, or on-land installations) to house and maintain the total system. Closed-cycle OTEC systems are suitable for installation on ships and, therefore, offer a potential way for OTEC plantships to draw power from the entire area of the tropical oceans and provide a major new source for renewable fuels production. 

High voltage transmission and distribution systems constitute critical infrastructures for the development and the prosperity of today s society. Substations and transmission lines form a network responsible for interconnecting the power generation facilities, from conventional and renewable sources, with the power consumption centers. In addition, further requirements are set, demanding the optimized operation of these installations with the highest degree of reliability and, at the same time, with the minimum possible cost.
