... WE dont need new dams, we need a big push on solar and EV.....
Hey man, don't dis dams.
For any solution to succeed and perpetuate it must be economically viable. The reason why hydro is the dominate renewable resource world wide is because it is economical and is (or was here) commercially viable.
Solar is not economical, and is only popular (overseas) due to subsidies. History has shown us that as soon a subsides disappear the behaviour they encourage frequently also disappears. Solar has gotten cheaper due to mass-manufacturing encouraged by foreign subsidies. Once foreign subsidies and demand tapers off, solar will likely go back up in price here.
Dams also compliment cyclic renewables (wind/solar/tide) as a highly effective energy storage solution beating any and all batteries made or in design so far, so are important regardless.
The RMA has been used to block the construction of new dams. People who block hydro frequently pass them selves off as environmentalists, however I for one are extremely dubious of their environmental claims. Anyone who cares about the global environment and wants to be a decent global citizen should be embracing commercially viable renewable energy.
Hey man :-)
I dont diss dams, although those that do complain about flooding the beauty and history we have here. And yes, I am very greebn as far as renewables are concerned.
My take was that I thought, clearly incorrectly, based on your and Andrew's post, that solar is the way to go. Domestically and commercially it can reduce power costs, good for the economy, and reduce the drain on hydro, allowing hydro to cater better, and also to allow all renewables to pick up soem slack as EV takes off.
I have solar HW, it was $8k in 2010, love it. My ex mother in law has Solar PV no batteries, unsure of kW a coup,le of years ago, my mate who I will get details has a 10KW Solar PV. I thought there was a reasonable number here with PV too, bit it seems to not stack up at all?
