Science and Technology The energy debate: Could our future be renewable?

Learning objectives: To know why carbon emissions are increasing To understand the solutions

“Despite public concern for climate change....carbon emissions are rising”...why? Read the sheet and decide which factors increase carbon emissions

Why have emissions increased? Buy a composter for food waste; uncooked food and vegetable peelings are stored and rot to form compost. Purchase appliances with an efficiency rating of A* Sign up to a ‘green tariff’ with your electricity company Insulate your loft and cavity walls reducing the loss of heat (energy) from your home. Recycle waste. Use council recycling centers and recycle from home Cycle. This healthy but also cuts CO₂ emissions. Many town centers have designated cycle lanes Kyoto Treaty (1997); an agreement by industrialized countries to reduce greenhouse gases Increase in car use. Over 40% of primary school children are driven to school. Population explosion; in 1900 the world population was 2 billion people; in 2000 it was 6 billion people. Increase in the number gadgets. In 1970 the average home had 17 gadgets and in 2005 the average home had 47. Cheap air flights; Fly to Prague for £20. A substantial growth in the cheap airlines, e.g. EasyJet and FlyBe Single occupancy; the number of homes have increased from 3 million in 1971 to over 7 million in 2005 Buy locally sourced food, in season. Purchase food from local markets instead of supermarkets. Buy a water butt for your garden. Rainwater is stored and used for watering plants. Road traffic has increased by 10% since 1997 Increase in food miles. One glass of orange juice is equal to 2 glasses of petrol Grow your own food. Allotments cost on average £20 year rent Leaving household items on standby; uses ½ the energy of leaving on Britain’s CO₂ emissions have doubled in just 10 years Congestion charge in London and Sydney. Drivers are charged for entering the city boundary Purchase energy saving light bulbs. Often more expensive to buy but can last up to 20 years. Reuse plastic bags from the supermarket or buy reusable bags. Collect ‘green’ points. Improving public transport in cities, e.g. Nottingham tram system, cycle lanes and park and ride Increase in car ownership. The average shopping trip is 4.3 miles Car sharing schemes. In USA car share drivers use the fast lane

What are the advantages of wind power?

1. The wind is free and with modern technology it can be captured efficiently. 2. Once the wind turbine is built the energy it produces does not cause green house gases or other pollutants. 3. Although wind turbines can be very tall each takes up only a small plot of land. 4. Many people find wind farms an interesting feature of the landscape. 5. Remote areas that are not connected to the electricity power grid can use wind turbines to produce their own supply. 6. Wind turbines also have a role to play in the third world. 7. Wind turbines are available in a range of sizes which means a vast range of people and businesses can use them.
