Lower
oil prices but more renewables: What’s going on?
Why the renewables sector is more resilient than
ever?
Not that long ago, the plunge in oil prices that has
occurred over the past year would have been to renewables what kryptonite was
to Superman, as the Financial Times put it. Not any more. Yes, it’s true that American investors would
have been better off putting their money into the S&P 500 from April 2014
to April 2015 than in clean-tech funds. That was the period that saw oil prices
drop from almost $100 to less than $50 a barrel, before recovering a bit. But
in the first quarter of 2015, many clean-tech funds handily outperformed the
S&P. Moreover, the sector did not see a wave of bankruptcies and pullbacks
like the one that scarred it a decade ago, when a glut of Chinese manufacturing
drove dozens of solar companies into oblivion. In fact, global clean-energy
investments increased 17 percent in 2014, reaching $270 billion, reversing two
years of declines. While government-policy support remains crucial, renewable
companies also did well raising money in the markets; equity investment rose 54
percent in 2014.
There are other
reasons for optimism. One is that deployment of renewable technologies
continues to rise. The United States is on course to install 12 gigawatts of
renewable capacity this year, more than all conventional sources combined. Wind capacity grew by 8.1 percent in 2014, and based on
its analysis of projects in the works, the US Energy Information Administration
(EIA) estimates capacity will grow another 13.1 percent in 2015 and 10.9
percent in 2016. Solar is growing even faster, though from a smaller base.
Between now and 2022, the EIA predicts that renewables will account for the
majority of new power; by 2040, its US market share could be 18 percent, up
from 13 percent in 2013.
Globally, 2014 saw a record 95 gigawatts of
new wind and solar, and the International Energy Agency (IEA) expects
renewables to account for 25 percent of power generation in 2018, up from 20
percent in 2011. In 2014, nonhydro renewables accounted for almost half (48
percent) of net new power capacity. This was the third year in a row the figure
was above 40 percent. Solar, in particular, is hitting its stride and has grown
an average of almost 30 percent a year for the past decade.
Why haven’t the much lower oil prices been
kryptonite for renewables? And what does this mean for the future?
Trends and possibilities
There are four main reasons why the link
between oil and renewables appears to be weakening.
They operate in
different markets. Oil is predominantly
used for transport—cars, trucks, planes. Very little of it is used for power;
oil accounts for less than 1 percent of power generation in the United States
and Canada, for example, and not much more in Europe. Globally, the figure is
around 5 percent. Renewables, in contrast, are used mostly to create
electricity. The more important factor for renewables, then, is not the price
of oil, but the price of electricity, and the latter is not entirely a function
of the cost of fuel. The electrical grid itself is expensive, which is why US
power costs, which are relatively low in global terms (an average of 12 cents
per kilowatt-hour), have been rising. In Europe and Japan, electricity costs
are significantly higher, and the relative position of renewables is
correspondingly better.
In some markets, oil is linked to the price of
gas, which is a major player in power production (27 percent in the United
States and 18.6 percent in Europe). In effect, gas becomes the floor price for
power, and in most markets, most renewables are still more expensive. So it is
certainly possible that cheap gas can drive out or at least slow the growth of
renewables. But that need not be crippling. To the extent that gas displaces
coal, that’s good for the environment, because gas is cleaner when it comes to
both greenhouse-gas emissions and air pollution. And this shift is already
happening. In the United States, the use of coal for power generation has
fallen from almost half in 2005 to 39 percent in 2014. That is a large part of
the reason that greenhouse gas–related emissions in the United States actually
fell over the same period.
And because energy investment is long term,
changes in the spot price of gas will not in themselves derail investment in
other sources. As long as renewables keep getting cheaper, there is room for
both. Also, it bears remembering that wind and solar are inherently
intermittent: the wind doesn’t blow on demand, and the sun sets every day.
Therefore, a backup source of power that can be switched on and off at will—as
coal, gas, and nuclear can—is essential for the industry. In this sense, cheap gas
can actually complement renewables.
The economics of
renewables are improving.
In 2011, when annual global investment in renewables peaked at $279 billion, 70
gigawatts were installed. In 2014, almost 40 percent more (95 gigawatts) was
installed, though investment was slightly lower, at $270 billion. In that
comparison lies the most important reason that renewables have held their own,
and then some, even as the oil price fell so drastically. To put it simply,
renewables are getting cheaper all the time. Moreover, most regulatory
supports, such as portfolio standards, tax credits, and feed-in tariffs, remain
in place. These do protect the sector to some degree, but the larger story is
that of fast-increasing competitiveness.
In the United States, the National Renewable
Energy Laboratory (NREL) estimated in 2014 that the cost of residential and
commercial solar photovoltaic (PV) systems fell an average of 6 to 7 percent a
year (depending on size) from 1998 to 2013, and by 12 to 15 percent from 2012
to 2013. Costs kept falling in the first half of 2014 and are expected to
continue to do so for the foreseeable future.
In fact, when it comes to the price of solar,
even the most optimistic estimates have not been optimistic enough. As NREL
notes, today’s price projections to 2020 are about half of what was being
predicted a decade ago. The IEA, which has had a reputation of being cautious
about renewables, now estimates that the “levelized” cost of solar PV (total
lifetime costs divided by total output) is at or near parity in many markets.
In the United States, McKinsey projects, solar will be competitive with
conventional fuels in most states by 2020. As for wind, it is generally the
cheapest nonhydro renewable; since 2009, its cost has fallen 58 percent, thanks
to less expensive materials and greater efficiency. As a result, wind is either
at or near to being competitive, on a cost-per-watt basis, without subsidy, in
a number of markets.
Crucially, there is no reason to believe that
the economics of renewables are going to deteriorate. Coal could get cleaner,
but no one really expects a big change in its efficiency, and tighter
regulation is driving up costs. For gas, the best technologies in use are
already highly efficient. But for renewables, particularly solar, substantive
improvements in cost and efficiency are not only possible but likely.
In production, for example, economies of scale
can be expected to continue driving down costs. More significant savings are
likely to come on the service side, known as “soft costs,” such as permitting,
licensing, and maintenance. In the United States, there is a wide variation in
the cost of installation; if and when best practices spread, one would expect
to see convergence at the lower end of the scale. And even the cheapest US
states (Florida, Texas, and Maine) are considerably more expensive than
Germany, which has driven down soft costs markedly. In 2013, it cost
Californians $4.94 to install a watt of solar; the figure for Germany was
$2.05. Cutting tariffs on foreign (meaning Chinese) modules would also lower
costs. There is a lot of room for improvement, and this holds true for many
global markets.
Counterintuitively, there is even a way in
which much lower oil and gas prices can actually help renewables. Many countries
have helped pay for the cost of fossil fuels through consumer subsidies; in
2012, the IEA estimated that these subsidies cost governments $544 billion. As
all subsidies do, these policies led to higher consumption than if people had
to pay the market price. When oil prices crashed, several countries in Africa,
as well as Egypt, India, Indonesia, Ukraine, and others, took the opportunity
to cut these subsidies. China raised gas taxes, which had the same effect of
dampening demand. When oil and gas prices increase, as they have already begun
to do, renewables will be in an improved relative position.
For governments and companies considering the
long term, one way to think about it is that the cost of conventional fuels may
go down. Or up. More likely, it will do both, as we have seen in 2014–15.
Renewables, in contrast, are going in one direction only: down. That’s an
intriguing proposition with regard to creating a resilient energy portfolio.
The global dynamics of
energy are changing. Because renewables
have been relatively expensive, historically, most investment has come from
developed countries; poorer ones felt they could not afford these energy
sources. In addition, oil-rich countries, many of them in places well suited
for solar, didn’t bother either, because they could burn cheap oil. Both of
those assumptions are swiftly changing.
In 2013, China for the first time invested
more in renewable energy than Europe, according to the United Nations, and is
now the global market leader. That year, new renewable capacity was greater
than any other kind. In 2014, China installed 11 gigawatts of solar, and there
are plans in the works for just as much this year. (China is also pouring money
into cleaner coal—a form of clean tech that many greens disdain but that could
be enormously beneficial.) Last year, China was the world’s biggest single
investor in renewables ($83.3 billion), almost 40 percent more than in 2013;
the United States was second ($38.3 billion), and Japan third.
Then there is India. Prime Minister Narendra
Modi wants to rely on solar in large part to bring power to the hundreds of
millions of Indians who lack it. While the country’s chief economic adviser,
Arvind Subramanian, acknowledged that “for the foreseeable future, India will
be reliant on coal,” the country’s ambitious goal is to install 170 gigawatts
of clean energy by 2022. India’s spending on clean energy rose 14 percent in
2014, to $7.4 billion. South Africa ($5.5 billion) is also getting serious
about the sector, as are countries in Latin America. In 2012, Mexico’s
president Felipe Calderón stated a goal of getting 35 percent of electricity
from low-carbon sources by 2024. According to a McKinsey analysis, even after
taking a hit due to the financial crisis, the region’s investments in solar
have risen 54 percent a year since 2008; in biomass, by 11 percent; and in
wind, by 24 percent. Brazil, Mexico, and Chile are leading the way. McKinsey
estimates that of the 40 gigawatts of new power Brazil will add by 2040, at
least 15 gigawatts will be renewable, mostly wind; for Mexico, the estimate for
renewables is 16 gigawatts by 2020. As a whole, developing countries accounted
for just a bit less than half ($131.3 billion) of global investment in clean
energy in 2014, and this figure rose much faster (36 percent) than spending in
the developed world (up 3 percent).
It’s also worth noting that some countries in
the Middle East are getting much more thoughtful about the possibilities of
solar. A Saudi conglomerate recently purchased a major Spanish solar developer,
Fotowatio Renewable Ventures, which has a pipeline of almost 4 gigawatts of
capacity. Egypt wants to increase renewables to 20 percent of capacity by 2020
and is nearing approval of a $3.5 billion, 2-gigawatt solar project with
Bahrain’s Terra Sola. And Dubai’s state utility signed a deal late last year
with a Saudi solar company for what could be the cheapest solar in the
world—less than six cents per kilowatt-hour. McKinsey estimates that even at
prices of $35 to $45 per barrel of oil, solar PV pays for itself—and that frees
up more oil for Saudi Arabia to sell.
Japan is also becoming a major player. In the
wake of the Fukushima nuclear accident in 2011, the government has markedly
increased its commitment to renewables. While nuclear accounted for 20 percent
of power generation in 2009, it was down to just 1 percent in 2013, according
to a McKinsey analysis. In 2011, the country introduced a “feed-in
tariff”—essentially, a guaranteed, above-market price—to encourage renewable
production. Solar-power installations soared. There have been problems
associated with this effort, with utilities saying they cannot economically
absorb the surge in capacity, but there seems little doubt that Japan will
continue on this course. The country is now the third-largest investor in
renewables, and McKinsey has found that the sector is now attractive enough
that many non-power players are entering the field.
The science is
improving. New solar
technologies could allow solar cells to be rolled out via 3-D printer and
applied almost anywhere. Japan is managing to make fuel cells work. Techniques
to convert manure into methane are getting cheaper. Perhaps most important,
storage is getting better and cheaper, and investment in the area is rising.
The biggest barrier to
the widespread deployment of nonhydro renewables is that they cannot be stored
for a rainy (or cloudy or windless) day. But there is good reason for optimism.
The energy density of batteries—that is, how much can be stored by weight—has
improved steadily over the past two decades, and the pace appears to be picking
up, with the price of storage down 60 percent in the past decade, according to
theEconomist.3 McKinsey estimates that the cost of producing lithium-ion
batteries, now about $400 per kilowatt-hour, could go as low as $150 by 2020.
IHS, an energy consultancy, estimates that storage installations will reach 40
gigawatts by 2017; and the market for energy storage could be as much as $70
billion over the next decade, according to Navigant Consulting.
With that kind of potential in play, many
smart minds are working hard on this. Major companies in the United States,
Europe, and Asia, for example, are pouring resources into storage technologies.
In early May, Tesla Motors launched two lithium-ion automated battery systems,
adapted from the technology used in its electric cars, which would allow even
small businesses and homes to store and release energy on demand. With a base
price of $3,000 to $3,500, these 220-pound batteries, known as the Powerwall,
could be at work as soon as this summer. At this price, storage becomes
economically feasible in a large percentage of buildings, depending on the
regulatory environment and cost of power.
The European Union is testing a project in
Ireland in which a motorized flywheel can harness surplus energy from the grid,
store it in turbines, and then release it on demand. The US Department of
Energy’s famous innovation lab, the Advanced Research Projects Agency–Energy,
is funding a dozen storage-related projects. It is not far-fetched to believe
these efforts will discover a variety of cost-effective solutions. The demand
for time-shifted energy storage, according to McKinsey, could grow ten times by
2050; that kind of potential attracts innovation. Getting there will require
regulatory creativity; however, McKinsey analysts note that at the moment,
there are price-signal distortions and a general lack of clarity about how to
integrate stored power into the system.
The long game
The world is not running out of fossil fuels
in the immediate term. There are enough known oil reserves for the next 53
years, and the rise of shale gas in the United States is an example of how
innovation and technology can change the game. Coal is abundant.
So the case for renewables cannot be that they
will keep the lights on as hydrocarbons thin out; this isn’t even a medium-term
concern. The better argument is that renewables are, by and large, cleaner than
the alternatives, and they provide a welcome diversity to energy supply and
therefore enhance national energy security. Even this would not be enough,
however, if renewables were expensive and/or unreliable. But on both these
dimensions, the sector is making great strides, and more can be expected.
That said, a sense of proportion is necessary.
Trends do not necessarily continue, nor should every bit of good news be
expanded, extrapolated, and hastened, as too often happens. Headlines that
proclaim the death of the car as we know it or the end of Big Oil are
premature. (Reality check: electric vehicles accounted for only 0.5 percent of
vehicle sales in 2014; conventional cars and hybrids the other 99.95 percent.)
And it’s worth remembering that the share of fossil fuels in primary-energy
consumption, a category that includes transport, didn’t budge a fraction
between 2005 and 2013, sticking at 87 percent.
Big, complicated change is not easy,
particularly when it comes to something as fundamental as energy. For developed
countries, incorporating renewables into existing electrical systems is proving
very difficult indeed. For example, former US energy secretary Steven Chu notes
that most of Germany’s wind power is in the north; to get it to industry in the
south means building transmission capacity—and that runs into “not in my
backyard” politics. American utilities are fighting policies that force them to
buy off-grid power at retail rates. Emerging markets without an extensive power
infrastructure in place will be able to skip these problems but will have to
deal with issues of access, finance, stability of supply, and the rising
expectations of their citizens.
In short, a world powered by renewables is not around the
corner. This will be a long-term transition—a matter of decades, not years. But
the resiliency of the sector in the face of much lower oil and gas prices is a
sign that it may just be on its way.
