Overview
All energy sources (fossil fuels as well as renewable energies) have some effect on our environment. Even though renewables are considered environmentally preferable to conventional sources (and, when replacing fossil fuels, have significant potential to reduce greenhouse gas emissions) it is still important to understand the impacts linked to the prodution of power from renewable sources.
The type and intensity of environmental impacts always varies depending on the specific technology used, the geographic location, and a number of other factors.

Technologies
Solar
The sun provides a tremendous resource for generating clean and sustainable electricity without toxic pollution or global warming emissions. The potential environmental impacts associated with solar power can vary greatly depending on the technology[1]:
Hydro
Although hydropower has no air quality impacts, construction and operation of hydropower dams can significantly affect natural river systems as well as fish and wildlife populations. Assessment of the environmental impacts of a specific hydropower facility requires case-by-case review.[2]
