I have reservations about Toyota's hybrid product for reasons mentioned here, the energy used to make these things, particularly the battery packs, seems to outweigh the good.
Now we have the Holden Volt - charge up overnight on 240 AC and drive to work and back on pure electricity - so in other words, lets burn more coal (that fires the turbines that generates our 240 AC) - so, to work and back on coal power - that's got to be good for the environment!
