WEBVTT 00:00.000 --> 00:12.080 Non-renewable energy resources are ancient, formed from the remains of plants and animals 00:12.080 --> 00:14.480 over millions of years. 00:14.480 --> 00:20.560 Unlike renewable sources, they can't be replenished within a human lifetime, making them finite 00:20.560 --> 00:25.040 and exhaustible. 00:25.040 --> 00:30.640 Oil is a liquid fossil fuel extracted from underground reservoirs. 00:30.640 --> 00:36.480 It's primarily used for transportation fuels, like gasoline and diesel, as well as for 00:36.480 --> 00:39.320 heating and electricity generation. 00:39.320 --> 00:44.880 Major producers include Saudi Arabia, the USA, and Russia. 00:44.880 --> 00:50.320 Oil is highly energy dense, easy to transport, and has versatile uses. 00:50.320 --> 00:56.320 However, its extraction and use come with significant environmental pollution, greenhouse 00:56.320 --> 01:02.160 gas emissions, and geopolitical tensions. 01:02.160 --> 01:08.400 Coal is a solid fossil fuel mine from underground or surface mines. 01:08.400 --> 01:15.760 It's mainly used for electricity generation, in power plants, and steel production in industries. 01:15.760 --> 01:22.000 China, the USA, and India are the largest coal producers. 01:22.000 --> 01:28.320 Coal is abundant in a reliable energy source, but it's a major contributor to CO2 emissions, 01:28.320 --> 01:34.160 air pollution, and land degradation from mining activities. 01:34.160 --> 01:39.120 Natural gas is a gaseous fossil fuel, primarily made of methane. 01:39.120 --> 01:46.640 It's used for heating, electricity generation, and as a feedstock in industrial processes. 01:46.640 --> 01:51.600 Russia, the USA, and Qatar are key producers. 01:51.600 --> 01:57.200 While natural gas is cleaner than coal and oil, its extraction methods, like fracking, 01:57.200 --> 02:05.920 have environmental impacts, and methane leaks, still contribute to greenhouse gas emissions. 02:05.920 --> 02:12.800 Non-renewable energy resources like oil, coal, and natural gas have powered the world for centuries. 02:13.680 --> 02:18.960 However, their environmental impact and finite supply make the transition 02:18.960 --> 02:25.760 to renewable energy sources increasingly important for our future.
