Energy Technologies

These pages summarise some of the energy technologies, with a focus on those that may be of particular interest to a hot country. Saving energy is cheaper than generating it. Using indigenous sources of energy is important not just to avoid political dependence but also because energy imports are likely to become ever more costly as rich industrialised countries buy up the remaining reserves.

Saving Energy

Saving energy is cheaper than generating it. In cold countries most energy used within houses is for space heating. Hot countries don't have to spend on heating but can end up using just as much energy for cooling using expensive complex air-conditioning equipment that has to be imported.


Transport is the other big energy user.
