Biofuels are of two main types: bio-ethanol and bio-diesel. Today bio-ethanol is by far the largest volume biofuel, and is produced from sugar cane as well as corn. Brazil is home to the sugar cane bio-ethanol business model, while the US relies on corn. Although sugar cane is much more economical and carbon-friendly, both crops require the diversion of high quality agricultural land from the production of food to the production of fuel.
In the case of Brazil, with it's huge land mass and tropical climate, the opportunity cost to food production may not be as critical. Hence, in Brazil, schemes such as using bio-ethanol as motor fuel and as feedstock for making plastics, are very effective in reducing CO2 emissions. In other countries such as India and Indonesia, which larger populations relative to land mass than Brazil, choosing between food production and biofuels production may not be an acceptable tradeoff.
Compared to biofuels, CRH offers the advantage that it does not need high quality land for energy capture. Out of the WHySGO energy range that CRH uses, for example in the case of Geothermal energy, there is no virtually no impact to land usage. Solar energy does imply land usage, but in desert climates where there is abundant land with no agriculture possible and high solar resource quality, there is no opportunity cost to deploying the land for CRH energy production.
