Technologies to get more out of the earth are progressing, but they don’t seem to be doing it as quickly as our demand is growing. In addition, while coal is much more abundant than oil, extraction of coal can be very unsafe, and is damaging to the environment on a large scale, causing erosion, acidification of the environment, and destruction of wild lands. Though the fossil fuels meet our energy and fuel needs, still it’s a high time to look forward for the alternative renewable sources of energy such as wind turbines, solar panels, tidal generators and compost. As said by a great man, there is enough for everyone’s need but not enough for everyone’s greed.
