Well, we seem to going in that direction - green energy & climate change & all - diesel is going to get more expensive with prohibitive taxes, solar is ultimately free and surely a more sensible form of power in the long term. Governments are paying fines if they don't meet their emission targets/promises, so they will definitely be raising taxes to encourage the take up of more environmentally friendly energy solutions; so as the adoption of cleaner technology becomes more widespread, it'll also become less complex & more efficient & less expensive.
Exactly.
