For most purposes; we''ll never get a better storage system than what we already have.; and unfortunately that isn't at all obvious to those who will expect both it staying free to them with preferred access and their subsidized miniscule input is used to design a new grid around a small totally "unreliable" solar generating capacity.

Of course its the existing electrical grid for most electrical customers/power producers.

[chuckChuck]

Currently there are limitations to what solar and wind can provide. But if solar electricity can be generated for 2-3 cents per kwh which is what some are saying is occurring in some countries already, then that will drive a lot of investment and research into storage and smart grid applications to use this abundant and fuel less electricity.

It is quite remarkable that Germany produces up to 40Mw of solar at peak periods.

We have grown up with relatively cheap finite fossil energy. It is difficult to see how this will change. But change is already happening and predicting the future and what technologies will succeed and fail or become obsolete is a mugs game.

I am not sure what will happen. But I am willing to bet solar pv will certainly be part of the future.

Our parents were still using horses and steam power to farm a few decades ago. Did any of them correctly predict the current technology that is used to farm and live our lives? No!

A couple good points chuck, but you also bring up the fact many of us are saying .
When , if this new energy tech becomes affordable and readily available to run our farms basic power needs - then implement a carbon tax . Until then it's a money grab wealth transfer that will do nothing to help the environment - at all.
Extra tax on alcohol and tobacco does curtail consumption. But a tax on fossil fuels just add an added expense that will show up in all inputs and deplete our net returns . The cost of T4 emissions has already driven up the machinery cost tremendously.
They are putting the cart way way before the horse with this carbon tax.

Chuck2, in Alberta a farmer can get 25% of his cost of installing a grid tie solar system payed for by government, up to .60 cent an installed watt if it is professionally installed and an energy audit is done. Also you are limited to net zero, so can only build a big enough system to produce what you use in a year. In my case if I remember right I use 18000 kWh per year. Requiring a roughly 12000 watt system. My house faces east and is surrounded by tree. Requiring a ground mount system which increases cost of installation by about 60% but improves performance by 7-14%. I will estimate 3.25 a watt. So 40 grand minus 7200 subsidy so 32800. Our Premier has set the price of electricity until 2021 at 6.8 cents a kilowatt. I signed a new contract with Enmax this am for 6.79 cents a kWh for 5 years today. My yearly electricity cost with all costs in is 3750 dollars. This will save me about 1230 dollars a year for a 32800 dollar investment. In Alberta your 2-3 cents cost of generation is a total fantasy. Even with the subsidy a 25 year payback. Your 3% increase per year for power doesn't apply in Alberta. Also your inverter only lasts 10-15 years then must be replaced. Getting very sick of your inability to face reality.

Having said everything that could be said; presenting the plluses and minuses and most of the consequences that might evolve; it is time to admit that some adhere to only what they know they knew.

I'm the first to admit that if somebody gives you a brand new car (subsidy gift etc) and a gas card with no expiry date and somebody else's address (courtesy the sun and what government will allow you use it for) and nothing ever wears out; has an accident and you don't get caught (or need a medical exam, driver's licence and insurance, new tires just to name a few)....then you can correctly tell the world it was all free and just like 2-3 cent/kwh solar electricity... you'd be saying that if anybody would follow your footsteps ....there need be no cost to transportation

But don't ever admit that its an oversimplification...maybe misinformation and could even say a deliberate deception on those who do not care or know better.


It just that someday you might appreciate that you got caught in the same net, all along; depending on fossil fuels for your operation...but was on the wrong side supporting those want it phased out now.

The facts will be in by 2019 for Sask Power and coal fired generation that both you and everyone else depend on in Sask for somewhat "affordable, dependable" electrical supplies. Don't use historical 3% cot increases The new norm is to ask twice yearly; get cut back a couple percent by rate review at about 8.5% and apply for 5% every 6 months. That and more is needed when things don't go as expected and luck isn't always a one way street.
Enjoy what you're touting...but it means nothing if you won't buy in


You confident in the next few years...or just bluffing???.

Oil industry prepares for the end of fossil fuel age

A roundup of what The Globe and Mail’s market strategist Scott Barlow is reading this morning on the Web

British Petroleum’s chief economist Spencer Dale believes that the longer-term future for the oil industry is less a matter of when we run out, and more a case of how much will be left in the ground after being replaced by alternative power,

“'I think it is increasingly likely that there will be technically recoverable oil reserves which will never be extracted and if I was the owner of one of those companies which owned that oil I would have every incentive to make sure it wasn’t mine [left in the ground].”' Pricing pressure is likely to come from the supply side, because of strong growth in US shale oil, and the demand side as the rise of renewable energy, including electric vehicles, gradually slows growth in oil consumption.”

“Oil rises on weaker dollar, U.S. supply caps gains” – Reuters

Whether I personally invest in any technology is irrelevant as we are all going to invest in wind, solar, and natural gas conversions through Saskpower.

If you don't think it is a good investment, make your case to your local MLA, Saskpower or the Premier.

By the way I have never advocated phasing out fossil fuels before we have affordable, better alternatives.

What is your response when the chief economist at British Petroleum is talking about the phase out of oil and fossil fuels because of renewables?

[chuckChuck]

Hamloc the situation in Alberta is different for Solar and your existing rates are much lower at 6.79 cents per kwh. In Saskatchewan with 11.8 cents per kwh the solar pv grid tie program will save you money in the long term. With an average 3% per year increases in price, by year 30 electricity could be 25 cents per kwh compared to the 10 cents you locked in with a current solar pv system.

Whether this is a good investment is up to individuals to decide.
