Renewable growth in the US: 1, 2, 3 March 14, 2015

They’re popping up like weeds!

Three reports that came out about the same time highlight the dramatic changes to the US power mix which is going on largely without comment outside the nerdy circles (like this one).

The long and short is this: wind power in the US will double to about 10% in the next five years, and make up something like 35% of the US grid by around 2050. That’s fast, but solar is going in ever faster, outpacing wind. Coal is disappearing, while gas turbines take up its place.

As always, this is really about cost. Wind turbines and gas plants are far, far less expensive than any non-hydro conventional source. PV isn’t that far behind. Coal plants are actually more expensive than any of these, nuclear even more. And that, basically, is that.

Future grid: energy and transport September 16, 2014

Do not open the door

I was watching the fairly silly Extant last night and saw a bit of tech that caught my eye; it was a burner cell-phone powered by a chemical reaction you started by twisting it like a glo-stick. It’s a little throwaway prop that I just love.

The reason I bring this up is that they also assume every car is electric. Nothing new there, but in this case they use an actual car instead of a made-for-TV model. Lots of Teslas and BMW i3’s.

And that got me thinking. What sort of overall effect is there on the grid if everyone starts driving electric? I know that electric cars use less power overall, but what sort of effect does that have on the big picture?

Well unless I’m doing the math seriously wrong, it looks like the answer is “bring it on!”

Hidden in plain sight: EIA highlights massive swing to renewables June 27, 2014

For many years the gold standard in energy reporting in the US has been the various EIA reports. Over the last five years though, it was clear something was going wrong. Renewables were part of the reports but always listed at high costs and low adoption rates. The numbers weren’t wrong, just outdated, as if you were reading a report from three years ago.

And this month’s report drives that home; the EIA has been predicting slow uptake of various renewables for some time now, and long predicted that it would reach about 13.5% of the electrical mix around 2040. However, the latest report, covering the first third of 2014, shows that renewables covered 14.04% of the electrical mix.

Wow.

PV outpaces Wind, in other news, River Styx very cold September 27, 2013

I’m not normally one for the blogroll, but I thought this little news tidbit was worth pointing out – PV is on track to install more new generation than wind for the first time.

According to Bloomberg, they’re expecting 36.7GW of PV, 33.8GW of onshore wind, and 1.7GW of offshore wind for 2013.

At least some of this is due to the massive upswing in PV in Japan, while at the same time we’re in a low point in wind due to the permanent boom-and-bust cycle in US wind installations, and a surprising uncertainty in China’s normally robust wind pipeline.

This is expected to reverse again as new builds come into the pipeline, but it’s an interesting point in history anyway.

Just a quick note…

A peer-reviewed report out of the UK demonstrates that wind can supply a major portion of their power supply, and all the negative concerns are, quite simply, not true. The report concluded:

“unequivocally that wind power can significantly reduce carbon emissions, is reliable, poses no threat to energy security and is technically capable of providing a significant proportion of the UK’s electricity with minimal impact on the existing operation of the grid”

And further…

“Claims to the contrary are not supported by the evidence”

In spite of this report, and many like it, I’m sure it will have no effect on the debate anywhere else. After all, the wind in the UK is made up of different molecules than it is here, right?
