Despite Low Oil Prices, Renewable Power Gaining Traction, Energy Agencies Report — But Not Yet Fast Enough for the Climate


The shift away from coal and towards renewable sources of energy is slowly beginning to gain traction, two recently-released reports from American and global energy agencies show.

The biggest story is in the case of renewables,” International Energy Agency executive director, Fatih Birol, told the Guardian as this year’s World Energy Outlook was released. “It is no longer a niche. Renewable energy has become a mainstream fuel, as of now.”

Almost half of the new power generation added in 2014 came from wind, solar, wave or tidal energy, the report found, and renewables now represent the world’s second largest source of electricity after coal. Coal, whose share of the world’s energy mix has been rising since 2000, has peaked, the agency indicated, predicting that within two decades, renewable energy sources will replace coal as the backbone of the world’s electricity source.

Domestically, the growth of renewable energy has been especially pronounced in Texas and other states long famous for their drilling and mining histories, data released by the U.S.-based Energy Information Administration shows.

Texas has become the largest wind-power supplier in the country, helping to slash as much carbon from the state’s emissions in 2013 as both Vermont and New Hampshire combined produced that year, if Texas had gotten that power through burning an equal mix of coal and natural gas instead of wind.

Still, the transition away from fossil fuels is coming too slowly to prevent catastrophic climate change, the IEA warned.

“There are unmistakeable signs that the much-needed global energy transition is underway,” the agency wrote in its report, “but not yet at a pace that leads to a lasting reversal of the trend of rising CO2 emissions.”

For the world to have a shot at keeping emissions below the 2 degree of warming threshold, the agency identified five key steps: the least-efficient coal plants must be banned, many fossil fuel subsidies must be ended, infrastructure like buildings and transportation need efficiency improvements, investment in renewable power must rise from $270 billion in 2014 to $400 billion by 2030, and methane leaks from oil and gas companies must be slashed.

The good news? Those measures could be taken at “no net economic cost,” the agency concluded.

All told, this year, renewable energy sources represented over 17 percent of the U.S. electrical generating capacity — an unprecedentedly high number, but still far less than fossil fuels.

Remaining dependent on fossil fuels brings economic as well as environmental risks. The IEA warned that while oil prices remain low currently, the cost of a barrel is expected to roughly double over time, and that in some situations, the world’s oil industry would be vulnerable to shocks that cause oil prices to spike.

But many policy makers have yet to absorb this message. Despite concerns about the environmental and economic prospects for fossil fuels, the oil, gas, and coal industries continue to benefit from roughly four times the amount of government subsidies as the renewable energy sector, the IEA said.

“[W]e estimate this global subsidy bill [for fossil fuel consumption] at around $490 billion in 2014, although it would have been around $610 billion without reforms enacted since 2009,” the agency wrote. “Subsidies to aid the deployment of renewable energy technologies in the power sector were $112 billion in 2014 (plus $23 billion for biofuels).”

Not Just CO2

While energy agencies are primarily focused on carbon emissions, evidence is growing that methane leaks from oil and gas drilling, fracking, pipelines, and other infrastructure pose a grave climate threat that the U.S. government has underestimated.

“Because of the increase in shale gas development over recent years, the total greenhouse gas emissions from fossil fuel use in the USA rose between 2009 and 2013, despite the decrease in carbon dioxide emissions,” Prof. Robert Howarth, a scientist whose pioneering work on methane emissions suggests that burning natural gas — which the IEA predicts will be the only fossil fuel to gain market share — may be even worse for the climate than burning coal, wrote in a peer-reviewed paper published in the journal Energy and Emission Control Technologies. 

Methane, especially from shale gas sites, is leaking from the gas industry at a far higher rate than previously believed, Howarth said, writing that while the Environmental Protection Agency estimates that leak rates are just 1.8 percent, those conclusions are based in part on flawed data collection.

The true methane leak rate, Howarth concluded after reviewing the available research, may in fact be more than 10 times that rate in some cases — and on average,12 percent.*

There are some signs that energy experts worldwide are increasingly taking note of the hazards of methane leaks.

“Emissions of methane, a powerful greenhouse gas, along the supply chain will dent the environmental credentials of gas if there is no concerted policy action to tackle these leaks,” the IEA noted in its report, though it also labeled the fuel “a good fit for a gradually decarbonising energy system.”

But the carbon emissions from burning natural gas are significant as well. In 2013, the U.S. produced roughly 2.17 billion tons of carbon from burning oil and 1.7 billion tons from burning coal — and another 1.4 billion tons came from burning natural gas, the EIA reported, making natural gas responsible for 26.7 percent of America’s CO2 pollution.

A Shift to Pure Renewables?

The Obama administration has made its support for an “all of the above” energy strategy that envisions increasing reliance on natural gas in the short term as a “bridge” to the eventual shift to renewable energy.

But even without subsidies, there are already some markets where renewable energy remains competitive against fossil fuels, even as oil and gas prices have nose-dived this year.

In Houston, TX a newly built solar plant is expected to provide electricity for an average of 4.8 cents per kilowatt hour for 20 years.  That’s roughly half a cent more than Houston’s fossil-fuel based power plants in today’s over-supplied market — but two cents per hour cheaper than the 5-year average cost of conventional fuels, highlighting the unpredictability of the market for those fuels.

And wind power in that state has become so abundant that the New York Times is reporting it is literally too cheap to meter at night.

Meanwhile, keeping oil and gas flowing is expected to become increasingly costly. The IEA estimates that “just to compensate for declining production at existing fields and to keep future output flat at today’s levels,” the oil industry will require $630 billion in investments.

And building new pipelines to deliver oil and gas from areas like shale drilling regions adds to the expected costs.

Keeping these project costs under control (contrary to numerous recent examples of overruns) will be vital to the future competitive positioning of gas,” the IEA said.

Crunching numbers like these has some environmentalists targeting a near-term transition away from all fossil fuels, not just oil and coal.

The impossible is becoming possible. The global breakthrough of renewable energy has happened much faster than anticipated,” Emily Rochon, global energy strategist at Greenpeace International, told EcoWatch. “We believe that with the right level of policy support, the world can deliver 100 percent renewable energy for all by 2050.”
