Explore the advantages and disadvantages of major energy sources, including renewable options like solar, wind, hydroelectric, and geothermal, alongside conventional sources like coal and oil. This concise analysis highlights critical factors such as pollution, cost, availability, and efficiency. Understand the environmental impacts, economic implications, and technological challenges associated with each energy type. This guide serves as a useful resource for anyone interested in the evolving landscape of energy production and its sustainability.

Who am I? • RENEWABLE BY THE WATER CYCLE • no pollution • after building the dam and power plant the resource itself is free
Who am I? • efficient energy source- a little provides a lot of energy • easy to mine and transport • plentiful amount • inexpensive
Who am I? • no pollution • INEXHAUSTIBLE • free source • operating costs of power plants are reasonable ONCE the mirrors and other equipment are installed
Who am I? • Expensive • sinking land • only available in a few places where magma is close to the surface • technological problems with rusting pipes and equipment
Who am I? • takes time to re-grow living things large enough to use for fuel. • Pollutes some • Large amount of land needed to grow crops creating competition for land
Who am I? • LIMITED AMOUNT • pollutes causing acid rain and air smog • causes erosion of land that is mined from • pollutes water during runoff • black lung disease prevalent in workers that mine it • contributes to global warming
Who am I? • few places allow for me to be steady • I don’t happen all the time • expensive to build turbines • requires a lot of space • not able to store energy made from me
Who am I? • RENEWABLE BY WATER CYCLE • Plentiful • burns cleanly • can be transported in existing natural gas lines • I can be used in fuel cells to power cars in the future
Who am I? • can pollute • explosive • very expensive to separate me from water
Who am I? • efficient energy source- a little of me provides a good amount of energy • Can easily be moved from place to place in pipelines or trucks or tanker ships • less expensive than many other forms of energy
Who am I? • dams disrupt animal life • building dams is expensive • not a lot of rivers can support dams and most suitable places have already been used
Who am I? • LIMITED AMOUNT • my spills contaminate and pollute the water environment • pollutes the air when burned • economic/political problems • cost is rising as it becomes more difficult to find me
Who am I? • less pollution than burning coal • RENEWABLE BY REPRODUCTION • reduction of the amount of waste • waste is readily available
Who am I? • expensive to build facilities- lots of mirrors require lots of money • I am not available all the time • storage of me is a problem • not very efficient- takes a lot of me to make a little electricity
Who am I? • LIMITED AMOUNT • Melt downs can put radiation into the environment. • Radioactive waste stays radioactive for hundreds of years. • expensive to build the reactors
Who am I? • LIMITED AMOUNT • leaks are dangerous and explosive • cost is rising as it becomes more difficult to find me
