There are activities to go with these also. Key question &nbsp; http://www.scienceshare.co.uk/videos/view/20099/ Biogas typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Comprised primarily of methane and carbon dioxide, biogas originates from biogenic material and is a type of biofuel. It's a product of the anaerobic digestion or fermentation of biodegradable materials such as manure or sewage, and can be used in CHP plants http://www.scienceshare.co.uk/videos/view/20098/ Another little flash animation taken from EfficienCity, a virtual demonstration of how real world communities around the UK can use renewable and energy efficient systems to enjoy lower greenhouse gas emissions, cheaper electricity and heating bills, and a more secure energy supply. http://www.scienceshare.co.uk/videos/view/20097/ A silent but informative introduction to how wave power works.
