... A challenge for PV generation is integration of the output power onto the electric grid. Without the use of large-scale energy storage -- a viable technology, but one that is still not considered economical -- PV is considered a variable generation resource owing to both the daily solar cycle and fluctuations in daily output due to weather conditions (clouds, precipitation, etc.)

... CSP plants with TES -- both the parabolic trough and central receiver variety -- have an oversized collector field that transfers energy to the storage system during the peak hours of the day. The steam turbines that generate electricity will typically be specified at lower wattages than the peak thermal output of the collector field (EPRI, 2009)

... For example, social concerns associated with wind development likely to be encountered during permitting include the following: general public acceptance; impact of the wind project on the "view-shed," or visual appearance of the project setting from different locations; potential effects from shadow flicker for residents living relatively near the wind farm, bird and bat kills, and potential noise impacts from mechanical systems and aerodynamic operation of the turbine. Environmental issues associated with wind energy include land use, soil erosion, and impacts on resident and migratory bird and animal populations.

... . The Union of Concerned Scientists also estimates that biomass emissions/energy output are about ten times lower for biomass plants than for natural gas plants, and are even lower in comparison to coal fired plants.6 A problem with using biomass as a fuel is the low energy density of biomass relative to fossil fuels.

... Conversion to electricity generation is the most common means of LFG utilization and is accomplished through the use of internal combustion engines, turbines, microturbines, and fuel cells. Major drivers affecting the economics of LFG are the quality and quantity of methane produced over a proposed power generation project time period.
