The 5 hurdles to that shiny, renewables-filled
future
David Crane, the outspoken former CEO of NRG Energy,
saw his last day in office earlier this month. NRG
Energy has chosen to turn over a new leaf with Crane's
resignation and the new year-or an old leaf, if the
appointment of the company's chief operating officer,
Mauricio Gutierrez to follow Crane is any indication.
Crane wrote a very heartfelt and supportive note to
his colleagues on his departure, full of positive points
and genuine affection. But Crane couldn't resist one
nicely worded jab-that clean energy is the future and we
must accept that now.
That's the part of Crane's note that stuck with me
longer than the rah-rah employees-are-awesome
cheerfulness and the smartly worded affirmations. And it
stuck with me not because I disagree-honestly, I would
love for clean energy to be the future-but I'm always
amazed at executive statements along these lines that
never, ever reveal just how tough that future is going
to be to reach-for utilities, for the employees of those
utilities and, yes, for customers of those utilities,
too.
The fact that Crane's statement was very similar to a
recent tweet that came floating across our magazine's
account in response to an article link about trying to
prep the grid for distributed energy came to mind as
well. (That note said that it was "incomprehensible"
that any utility wasn't prepared for distributed energy
right now.)
I don't think anyone, really, wouldn't love a
cleaner, less dirty energy future, but just saying it's
the future doesn't make that shiny future materialize
instantly. If just saying something made it happen, we'd
all be a lot sexier, healthier and richer.
Unfortunately, for a clean energy future, there are
still many, many issues to overcome and many, many
investments to be made.
If we really want clean energy to be our future, here
are the five problems you must solve, Crane and company:
1. The issue of status
quo.
Fossils are still your big gen player, whether
you like it or not. According to EIA numbers for Oct.
2015, natural gas leads with 110,000 MW. Coal is a very
close second at 97,000 MW. Then comes nuclear at 60,000
and hydropower at 17,000. Then you get to the renewables
numbers, with wind being the biggest boost at 16,000.
Now, wanting those generation numbers from the bottom to
be at the top isn't crazy, but even with great planning,
it's not going to happen tomorrow (or within "immediate
future" timeframe many discuss). I don't say that to be
mean. To really make that change, you've got to
understand your hurdles here-namely replacing 210,000 MW
of fossil fuels or 300,000 if you add in nuclear, too.
Them's a lot of MW to switch out, which means a lot of
effort, time and money.
2. The issue of
capitalism-or lack therof, really.
So, let's talk money. Who's paying for this big gen
flip-flop? Customers think it should be utilities, of
course. But utilities are set up to recover costs
through approved regulated fees-basically paying for
upgrades and issues through their customer base.
Customers may want utilities to see this simply as a
good business investment for the future, but, in many
cases, utilities aren't like your local grocery store or
car dealer or even Apple. They can't up their product's
price because it's better, faster, more reliable,
healthier. They don't have that option. Regulators are
stuck in between trying to balance needs and wants. And
we haven't even started on the amount of subsidies that
renewables currently get for development and marketing
that fossil fuels don't-and they still don't come equal
to pricing yet. I'm not saying that can't happen or
won't happen. It simply hasn't yet. So, we're all still
looking for the money: customers, utilities, developers
and the like. And we all see different people paying for
that clean energy future. That's a problem.
3. The issue of cheap
power.
Here's another problem: Customers dig cheap power and
most of them are used to it, especially in the Midwest
and the South. The average residential retail price
(again, according to EIA numbers for October 2015) was
12.73 cents per kilowatt hour. Will customers pay more
for cleaner power? No study can come to a consensus on
this, and the percentage runs from none to nearly 70
percent, but it honestly depends on the price you're
pitching. One cent an hour more or two? You'll get
closer to that higher number (perhaps until they figure
out what that costs per year), but the higher those cost
numbers go, the lower the percentage of customers
willing to kick in that money. Would it be cheaper,
perhaps, for customers to invest in their own tech?
Possibly. Now, how many are willing to make that
investment up front? And, who is compensating the
utility for having to upgrade a grid system set to work
one way and now must work two?
4. The issue of hardware.
When friends ask me to explain why it's such an issue to
switch from the current big-power system to more
renewables, I use a transportation analogy. I say: Let's
talk trains. Let's say you have a massive regional train
system: tracks, maintenance yards, skilled workers,
infrastructure. Now, the powers that be come along and
tell you that they want to be able to go to the same
places along the same routes but in either a car, a boat
or on a bicycle. No more trains. Now, you're doing
essentially the same function: moving people along the
same routes. But moving people on a train a different
set of hardware involved than moving people in cars or
in boats or on bicycles. Some hardware and
infrastructure may translate. Some doesn't. So, it's not
all as easy as saying: "hey, it's all electricity"
anymore than it is saying "hey, it's all
transportation."
One-way systems into two-way systems. Adaptations to
substations and meters and distribution widgets and
gadgets. A need to figure out intermittency issues.
There's a lot of smart adaptations that need to be made
to our existing infrastructure for it to work more with
renewables. And that adaptation takes time. And there's
one big, big science issue that's yet to be really
solved.
5. The issue of physics.
Electricity cannot be stored like an average commodity
since it's an energy flow. So, basically, you're
converting electricity into other forms: magnetic fields
for inductors, electrostatic charges for capacitors,
chemical storage for most batteries. You can charge a
battery, yes, but that battery isn't a perfect system.
It can't hold that charge forever, and it takes more
power to charge than it stores. Combine that with a
constant need for power and you realize how we ended up
at #1: The one way to create power as needed to meet
demand is to burn something that gives off energy at a
predictable, steady rate. In all honesty, your biggest
hurdle to 100 percent renewables tomorrow is right here.
The sun doesn't shine all the time. The wind doesn't
blow all the time. The tide doesn't come in at a steady,
uniform, hourly rate. So, you need storage to
compensate. Unfortunately, our storage options aren't
perfect. As one K-State professor and former IEEE leader
told me in an interview once: She tells her students
that they could have the college named after them if
they could only solve the storage problem, really solve
it.
In the end, we all have to understand the obstacle of
#1. Regulators and the government will need to work on
#2. Customers will have to tackle #3. Utilities are
already working on #4, and #5 remains, as always, the
wild card.
Heart and souls are already behind this clean energy
future, but what we need now is a solid plan with actual
solutions to these 5 issues. If you want that fairytale
happy ending of clean energy, it's time to roll up
sleeves and get to down to the actual business of
setting those foundations right now. And no amount of
magical thinking will make it happen without tackling
these issues. You want to really get there? Stop
thinking positively and start thinking pragmatically.
We've got to mind the gap between our status quo and
that clean energy future everyone keeps touting, or we
will fall in.
