In its predictions for the next 30 years, the US Energy Information Administration '''[http://www.eia.gov/forecasts/aeo/assumptions/pdf/international.pdf predicts]''' that by 2035 the crude oil price will be in the range $50-200 per barrel, with the most likely scenario predicting around $125 per barrel (2009 dollars).  Likewise, the '''[http://ec.europa.eu/energy/observatory/trends_2030/doc/trends_to_2030_update_2009.pdf European Union predicts]''' a price of $106 per barrel by 2030 (2008 dollars).  (For comparison, oil prices have been in the range $80-110 during 2012, and are [http://www.oil-price.net/ currently around $80]).  Natural gas prices are also expected to hold fairly steady, and become slightly more competitive with oil.  Some experts concur with this opinion, as [http://www.usnews.com/opinion/blogs/economic-intelligence/2012/02/29/has-the-peak-oil-tipping-point-arrived here], but others [http://www.nature.com/nature/journal/v481/n7382/full/481433a.html disagree] (see [http://www.alaskadispatch.com/article/oil-tipping-point-has-passed-much-higher-prices-come this summary]).  The "tipping point" advocates argue that supply is leveling off at around 75 million barrels per day at a time *crude oil and lease condensate only) when consumption in [[http://www.indexmundi.com/energy.aspx?country=cn&product=oil&graph=consumption China] and [http://www.indexmundi.com/g/g.aspx?c=in&v=91 India] is soaring.  Some argue that new cheap reserves have been found, but others [http://ftalphaville.ft.com/blog/2012/07/24/1094111/is-peak-oil-dead/ question these assumptions].

Future energy: Solar/wind or fossil fuels

Solar & wind are now becoming cheap enough to compete with fossil fuels, and now 30% of electricity in the EU comes from renewables (of which solar/wind comprise 11% - rising rapidly). By 2050, the EU expects to have much of its power from renewables (see p33). In contrast, the US Energy Information Administration predicts that fossil fuels will still dominate US power production in 2040, with renewables predicted to only contribute 17% of the total by 2040. Are the Europeans just optimistic and the US realistic, or are the US forecasters stuck in the fossil fuel past? What about trying to reduce CO2 emissions?

Use of biomass as a resource

Is the biorefinery idea mentioned in Hill a viable one? Consider the pros and cons of biological material resources.
