Energy Basics

[b]Renewable energy[/b] is an energy source/fuel type that can regenerate and can replenish itself indefinitely through natural means. [b]Non-renewable energy[/b], in contrast, cannot - so it will one day run out. [h3]There are renewable and non-renewable sources of energy:[/h3] [b]Renewable:[/b] [ul] [li]Bio-Mass[/li] [li]Solar[/li] [li]Geo-Thermal[/li] [li]Tidal[/li] [li]Wind[/li] [li]Wood[/li] [/ul] [b]Non-renewable sources of energy:[/b] [ul] [li]Coal[/li] [li]Oil[/li] [li]Natural Gas[/li] [ul] [i]and Nuclear to an extent[/i] [highlight]Nuclear energy can be seen as [b]non-renewable[/b] as, despite it producing less waste than the other non-renewable sources of energy, it, like them, is in finite amounts[/highlight] [h3]Forms of energy:[/h3] [ul] [li]Sound[/li] [li]Electric[/li] [li]Thermal[/li] [li]Light[/li] [li]Kinetic[/li] [li]Elastic[/li] [li]Gravitation Potential[/li] [li]Chemical[/li] [li]Nuclear[/li] [/ul] [h3]Energy Transfer Examples[/h3] [ol] [li]A TV set transfers [b]electrical[/b] energy to [b]light[/b] energy[/li] [li]A match transfers [b]kinetic[/b] energy to [b]thermal[/b] energy[/li] [li]A light-bulb transfers [b]electrical[/b] energy to [b]light[/b] energy[/li] [li]A catapult transfers [b]elastic-potential[/b] energy to [b]kinetic[/b] energy[/li] [li]A falling bucket transfers [b]gravitational-potential[/b] energy (when stationary), to [b]kinetic[/b] energy, when in motion[/li] [/ol]
