Deaths caused by use of fossil fuels such as oil (areas of rectangles in chart) greatly exceed those resulting from production of renewable energy (rectangles barely visible in chart). [ 45 ] Some harmful impacts of petroleum can be limited to the geographic locations where it is produced, consumed, and/or disposed.
Oil depletion is the decline in oil production of a well, oil field, or geographic area. [1] The Hubbert peak theory makes predictions of production rates based on prior discovery rates and anticipated production rates. Hubbert curves predict that the production curves of non-renewing resources approximate a bell curve.
Oil rigs and oil platforms are used to drill long holes into the earth to create an oil well and extract petroleum. After extraction, oil is refined to make gasoline and other products such as tires and refrigerators. Extraction of petroleum can be dangerous and have led to oil spills. [1]
According to this, production of a barrel of shale oil can generate up to 1.5 tonnes of semi-coke, which may occupy up to 25% greater volume than the original shale. [3] This is not confirmed by the results of Estonia's oil shale industry. The mining and processing of about one billion tonnes of oil shale in Estonia has created about 360-370 ...
Oil palms produce 38% of the world's vegetable-oil output on 6% of the world's vegetable-oil farmland. [1] Palm oil plantations, typically monoculture crops are under increasing scrutiny for their effects on the environment, including loss of carbon-sequestering, biodiverse forest land. [2]
According to the IPCC Fourth Assessment Report, [51] in 2004 natural gas produced about 5,300 Mt/yr of CO 2 emissions, while coal and oil produced 10,600 and 10,200 respectively (Figure 4.4); but by 2030, according to an updated version of the SRES B2 emissions scenario, natural gas would be the source of 11,000 Mt/yr, with coal and oil now ...
Human activity since industrialization has led to a huge increase in the production of carbon dioxide, a greenhouse gas that contributes to rising global temperatures. Scientists warn that if carbon dioxide and other greenhouse gas emissions continue to rise at their current rates, Earth’s temperatures could increase dramatically in future ...
The Hirsch report, the commonly referred to name for the report Peaking of World Oil Production: Impacts, Mitigation, and Risk Management, was created by request for the US Department of Energy and published in February 2005. [1]
