This document discusses different types of resources including renewable, non-renewable, and sustainable resources. It provides examples of various energy resources such as coal, wind, natural gas, uranium, tides, wood, solar, and wave power. For each resource it describes what it is, where it comes from, how it is used, and environmental impacts. The document also discusses models by Esther Boserup and Thomas Malthus on population growth and resource availability.

Different Types Of Resources In pairs, DEFINE the term ‘resource’, prize for the best effort. ‘a naturally occurring product (wood, coal, wind) that can be used in its own right made into something else’
By the end of the lesson… • ALL of you will be able to name one type of resource. • MOST of you will be able to define the terms sustainable, renewable and non-renewable. • SOME of you will be able to state the benefits (good points) and costs (bad points) of at least one type of energy source.
Odd One Out and Why?
Classifying Resources Renewable They will never run out and can be used over and over again. Non-renewable These are being used up and cannot be replaced. Sustainable These are meeting the needs of people now, without preventing future generations from meeting theirs.
Coal A fossil fuel that was formed millions of years ago from the remains of dead trees. It is used as a domestic fuel (heating in homes) and to generate electricity in coal fired power stations. Burning it releases a lot of carbon dioxide into the atmosphere. Wind This can be used to turn wind turbines that generate electricity. Wind energy is very environmentally friendly and the UK has the potential to generate almost all of it’s electricity through wind farms. However, they can be limited by the frequency of the wind. Natural Gas Natural gas is used for electricity production, heating and cooking in Europe. It was created approximately 350 million years ago when tiny marine organisms died and sank to the bottom of the sea. It’s a type of fossil fuel and emits carbon dioxide when it is burned. Much of the UK’s North Sea gas has now been used up. Uranium This mineral is used to generate huge amounts of heat needed to create nuclear energy, a valuable method of electricity generation. Nuclear energy produces very little pollution, however it creates potentially dangerous radioactive waste that can cause severe illness and damage to the environment. Tides These regular changes in the height of the sea can be used to turn underwater turbines to generate electricity. They are very reliable, but as to date this type of energy generation is still in the research and development phase. Wood Produced by the growth of timber (trees). A very important resource that has multiple uses such as: paper, fuel and construction. Apples A fruit that is grown commercially as a food stuff throughout the world. Biogas This resource is created by the decomposition (break down) of organic matter such as wood chips and animal dung. This releases methane gas that can be used to provide electricity or burnt as fuel source. Solar The primary source of all the Earth’s energy, the Sun is vitally important to grow crops, rear animals and maintain the Earth’s temperature. In recent years scientists have developed the use of solar panels to generate electricity and heat water. Solar energy production creates virtually no pollution. Vegetable Oil Produced by the growth of plants such as palm nuts, vegetable oil is important for cooking, heating and as an ingredient in cosmetics and food products. Many of the worlds tropical rainforests are being chopped down to be replaced by palm plantations, destroying the habitats of many endangered species and contributing to climate change. Wave Power 40% of the worlds population lives at the coast. The energy from waves could be used to turn turbines to generate electricity. Still in its infancy this type of energy production is very rarely used, despite being environmentally friendly. Beef Produced from the rearing of cows, beef is a vital food product used around the world. As people become richer they are tending to eat more meat in their diets. Many parts of the biosphere have, or are being altered by cattle ranching. Cows produce methane, a greenhouse gas which contributes to climate change.
The Current UK Energy Mix 1. Describe the current energy mix of the UK using figures from the table. 2. How has energy consumption changed from 1965 to 2005?
Are There Enough Resources?
Esther Boserup • In 1965 Boserup wrote "necessity is the mother of invention". That means, if you need it, someone will invent it. • So if more food was needed she wrote that people would invent ways of increasing food supply - crops that fight diseases or survive with less water are examples of this.
Thomas Malthus • In the 18th century Malthus wrote that the rate of population growth was faster than the rate that food supplies could grow. In time, there would not be enough resources for everyone. Some people would therefore starve and the population would reduce again. • More people may be killed from wars over trying to get hold of resources - he called these a positive check. People might try to prevent this from happening by having smaller families. He called this a preventative check.
