Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project back no pollution renewable periodic danger remote areas climate farming eye sore cheap WIND POWER noise

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Wind power produces no water or air pollution that can contaminate the environment.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Wind towers can be beneficial for people living permanently, or temporally, in remote areas.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Overall wind power is cheap.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Wind power is periodic in many locations because consistent wind is needed for continuous power generation.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Large amounts of windmills can be an eye sore for the countryside.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Farming and grazing can still take place on land occupied by wind turbines.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project The effect of large-scale wind farms on the climate is unknown.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Wind generation is a renewable source of energy meaning we will never run out of it.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Wind farms can negatively affect bird migration patterns and pose a danger to the birds themselves.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project back store heating remote expensive no pollution not completely renewable SOLAR POWER

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Solar energy can be used very efficiently for both heating and lighting.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project It would be necessary to store solar energy if it is not used as it is generated.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Solar power is not always completely predictable because it depends on amounts of sunlight.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project In sunny countries, solar power can be used in remote locations.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Solar power is totally non - polluting.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Solar power is a renewable resource. As long as the Sun exists, its energy will reach the Earth.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Some forms of solar power are extremely expensive.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project back less cost no effect emissions abundant waste stench BIOMASS POWER

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Biomass production can be used to burn organic waste products resulting from agriculture

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Biomass is abundant on Earth and is generally renewable. In theory, we will never run out of organic waste.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Biomass energy product has little or no effect on the environment.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Direct combustion without emissions filtering generally leads to air pollution similar to that from fossil fuels.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Biomass can have a bad smell.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Producing liquid fuels from biomass is generally less cost effective than from petroleum.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project back constantly expensive renewable forests dangerous no pollution supply increase secure impact HYDROELETRIC POWER

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Hydroeletric power station can quickly increase to full capacity, unlike other types of power stations.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Electricity can be generated constantly because there are no outside forces.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Hydroeletric power produces no waste or pollution.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Hydropower is a renewable resource; the Earth is ¾ water.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Hydroeletric secures a country’s access to energy supplies.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project The construction of a dam have a serious environmental impact on the surrounding areas.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Dams are expensive to build, making start-up costs difficult.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Hydroeletricity can only be used in areas where there is a large supply of water.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Flooding submarges large forests. As the vegetation dacays, is releases methane, a greenhouse gas.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project Dams can be very dangerous for people who live under them if they break-down.

Teachers:MariaCinquina,RobertaConti Teachers: Maria Cinquina, Roberta Conti School Year 2007/2008 Comenius Project The wind-blades can make an annoying noise for the neighbourhood.
