Non-renewable energy

Consequently, the net OLR has increased by 0.006 W m-2 since 1880. This means that about one-third of today s thermal pollution (0.02 W m-2) is emitted from Earth. In the long term our use of non-renewable energy will cause a global temperature increase up to a point where the net OLR balances the net heat generation. Meanwhile, nature has some means of delaying global warming. 

The future steady-state global temperature was estimated by assuming that continued warming follows the same pattern as during the last century. This means that the previous LAT/SST increase ratio of 2.4 was assumed constant. Therefore, the land area temperature increase was assumed a factor 2.4 greater than the sea surface temperature increase. Today s consumption of non-renewable energy was also assumed unchanged. 

Earth counteracts global warming by its natural cold sources. This has started to show as a temperature increase of ground, air and water. Ice fields and glaciers offer another huge cold reserve and the world s total non-renewable energy use would annually melt only about 0.003% of current ice, with present use of non-renewable energy and no other cold source. 

Non-renewable energy resources fossil fuels - supply and future availability... 

Substitution of non-renewable energy sources by renewable ones. 

The major alternative is coal but this is also a non-renewable energy source with a predicted useful lifetime of about 200 years. 

Non-renewable energy sources Sources of energy, such as fossil fuels, which take millions of years to form and which we are using up at a rapid rate. 

The mineral coal reserves are one of the most important non-renewable energy sources in the world [3]. The same is true when it refers to the Brazilian energy context where they represent 60% of our non-renewable energy sources. The largest reserves are located in South Brazil and, as in other countries with large coal reserves, SCFE is here proposed as an upgrading process for Brazilian mineral coal. 

ProductiOTi and use of polymer products is environmentally disadvantageous wherever other materials perform the same function with less impacton the environment. Which types of materials these may be again depends on the specific function. Depending on the polymer type between 25 and several 100s Ml of non-renewable energy resources are consumed for the production of 1 kg of polymer. In the polymer s end-of-life tuily a fraction of 15-50 MJ, which is embodied in the polymer can be recovered for example as electricity and steam from waste incineration plants. Furthermore, new incineration plants are able to recover quality hydrochloric acid from the chlorine content of the polymers (and of course other non-polymer chlorine inputs). The remainder is lost. Production of synthetic polymers indeed consumes a high amount of energy, of which only a share can be recovered. While polymers are not per se environmentally bad, but in contrast often the better material alternative, they nevertheless must not be wasted, of course.
