Fracking, tar sand, shale oil: „immense historical error“ / Short term profit interests decide about investments
With oil prices rising, „unconventional“ oil and gas resources become attractive for investors: tar sands, shale oil and shale gas, which is extracted by a controversial technology called „fracking“. The exploitation of these sources is an „immense historical error“, Bardi says. Fracking might be even more climate-damaging than coal, as it releases Methane, a powerful greenhouse gas. Additonally, groundwater resources in vast areas have already been polluted by fracking, as in the US. Renewable energies are able to deliver much cheaper and cleaner energy – if environmental costs are taken into account. However, the system is not conceived to make such decisions, as it focusses only on short term, immediate profits."
