Personally I would like to see more development on wave/tidal systems, in sunnier climates more use of the sun for energy and in windier ones more wind farms. Hopefully in the near future building design would improve the efficiency of water usage and minimise heating/air conditioning as well having to generate its own power supply for at least heating water and possibly more.
i don't understand why those useless 'representatives' of the public in parliament don't just pass a bill amending the building regulation code to require houses to have solar panels. surely it can;t add too much more onto the cost of a house, and would save the owner a lot on power in the long run.
i saw a million dollar type house in queenstown that was completely powered by solar.
if something like this came in, peope would start manufacturing cheaper solar panels and the whole process would be less expensive for the house owners.
