Other renewable energy systems

In all the scenarios considered in this Outlook, increased deployment of other forms of renewable electricity, heating, cooling and transport fuels is projected. However, the prospect of climate change introduces uncertainties which could affect virtually all forms of renewable energy.

Wind resource intensity and duration can affect turbine capacity factors and extreme gales may damage turbines and shorten their working life.

■ Solar radiation levels are subject to reductions of up to 20% in some regions (Bull et al., 2007), due to increased cloud cover, and there is a risk of damage to solar collection facilities from extreme weather conditions, such as hail. In addition, higher ambient temperatures can reduce the output and life of photovoltaic cells.

■ Biomass may experience lower crop yields due to water shortages and increased warming, though higher atmospheric CO2 levels will increase crop and forest growth rates. There could be effects on biomass use for traditional cooking and heating purposes as well on biofuel production for transport fuels. Longer frost-free periods and fewer freezes can benefit some crops more than others, and there will be regional differences, with Africa and southern Asia more likely to be adversely affected than Russia (Lobell et al., 2008).

Geothermal power generation will be less efficient if warmer water or air is used for cooling. This will also apply to thermal power plants.

Getting Started With Solar

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
