Combustibles fósiles
Los combustibles fósiles o combustibles minerales son mezclas de compuestos orgánicos que se extraen del subsuelo con el objetivo de producir energía por combustión. Se consideran combustibles fósiles al carbón, procedente de bosques del periodo carbonífero, al petróleo y el gas natural procedente de otros organismos.

The peak oil debate is a case of history repeating itself: people have been ignoring warnings about exponential use of finite resources for a century and a half. No-one wants to hear the argument. Even International Energy Agency forecasts of record world oil demand, and warnings that the era of cheap oil is over made barely a ripple in the media.
Although climate change, decreasing exports, and depleting mineral resources will all eventually impact China's ability to grow economically, the availability and affordability of oil is still likely to impact first.
I've written lately that economists are the high priests of Progress. I don't subscribe to the doctrine of Progress, which is a faith-based view of our future. Apparently, for most people all of the time, the alternative is simply unthinkable. The truth is that we had wars 4,000 years ago, and we have wars now. The large majority of human beings were poor and disenfranchised 4,000 years ago, and the large majority still are today.
The balanced personality would want three things: 1) That we have a reasonably large stockpile of critical goods in case of a temporary disruption of flows, 2) that what we rely on for our survival be by and large renewable, and 3) that our demand for renewable resources would come into balance with the supply we can reasonably expect--considerably less than fossil fuels have provided us.
For a few days last week, global news agencies pursued the peculiar story of the world's worst traffic jam, which was reported to have lasted for around nine days and stretched across about 100 kilometres of a major highway leading to Beijing. China's latest instance of leading the world, now in the scale and size of traffic jams, is a direct consequence of the modern uses and abuses of energy.

Transport Revolutions presents an ambitious vision of a world, 15 years from now, that is well on its way to kicking oil and being run on renewably produced electricity. The books authors, internationally recognized transport policy experts Richard Gilbert and Anthony Perl, readily acknowledge the enormity of this challenge, with transport worldwide currently 95 percent dependent on oil.
Everyone knows that it takes energy to produce anything. The energy used in mining, transport, processing, manufacturing, delivery, and disposal is “embodied” in every product we consume, from food to diapers to televisions and insurance policies. Our traditional way of looking at energy, however, highlights only current consumption, traditionally disaggregated into agricultural, industrial, transportation, commercial, and residential sectors.
Every year the National Conference of State Legislators (NCSL) holds an annual conference where legislators from all over the US gather for updates on major public policy issues facing the nation. This year the organization found that issues surrounding our countrys future energy supply were becoming of such paramount importance to state governments that it set up a task force to study the issues; produced a report on meeting the energy challenges; and devoted a whole day prior to the annual meeting to an Energy Policy Summit where some 15 speakers gave presentations on various aspects of energy.
