Do Oil Companies aquire Alternative Energy Patents to Limit Technological Innovation, in order to Maintain Economic Advantage in Fossil Fuels
This paper addresses the charge made by environmental groups that oil companies, since the 1970's, have been acquiring alternative energy patents, to restrict these technologies from reaching the market. The purpose of these restrictions was to protect profits from oil, natural gas and coal. In …

Climate Change and the Exhaustion of Fossil Energy and Mineral Resources
The ongoing exhaustion of fossil fuels places a limit to the total amount of anthropogenic CO2 that will be emitted into the atmosphere and therefore constraints future global warming. Here we assess the implications of fossil fuels depletion on future changes of atmospheric CO2 concentration and …
