Google: Energy innovation will pay off but..

The folks at Google, not surprisingly, have enormous faith in the power of technology. So a group of them set out to see what technology breakthroughs in clean energy will mean to the economy, the environment and the typical American household.

They found good and bad news.

The good: Energy innovation could pay off big, benefiting GDP, jobs, energy security and reducing carbon emissions. It’ll even save homeowners money, over time.

Specifically, as Bill Weihl and Charles Baron write on the Google blog, here are the benefits of energy breakthroughs, when compared with a business as usual scenario. In their parentheses is even better news; those numbers reflect what clean energy technology can do when combined with stronger U.S. policy to promote clean energy and discourage the burning of fossil fuels:

  • Grow GDP by over $155 billion/year ($244 billion in our Clean Policy scenario)
  • Create over 1.1 million new full-time jobs/year (1.9 million with Clean Policy)
  • Reduce household energy costs by over $942/year ($995 with Clean Policy)
  • Reduce U.S. oil consumption by over 1.1 billion barrels/year
  • Reduce U.S. total carbon emissions by 13% in 2030 (21% with Clean Policy)

The not-so-good news is the last bullet: Reducing U.S. carbon emission by 13% by 2030, or even 21% under the more favorable clean policy scenario, won’t do much to reduce the threat of catastrophic climate change. The report also found that by  2050, innovation in the modeled technologies alone reduced CO2 emissions by 55% and by 63% when combined with policy. Those are under best-case assumptions.

But, while there’s lots of disagreement about all this, many reputable scientists, using respected climate models, say the world needs to reduce CO2 emissions by 70 to  80% by 2050, and that the U.S. share should be close to 80%. Here’s the argument, as articulated by the Union of Concerned Scientists.

So, yes, by all means, let’s invest in clean energy technology because it will be good for the economy in the long-term but let’s also be clear-headed about how terribly difficult it is going to be to head off something that looks like a climate catastrophe.  As White House science advisor John Holdren has said, there are fundamentally three ways to deal with the climate threat–mitigate, adapt and suffer–and this report suggests that we (more likely, our children or grandchildren) need to prepare for all three.

The report “highlights how hard the problem is,” Google’s clean energy czar Bill Weihl told me by phone last week. “Coal plants last a long time.”

Yes, they do, and they will even if the costs of clean energy drop sharply. Here’s a chart showing the U.S. power generation mix in 2030 under a variety of scenarios modeled by Google, using McKinsey’s Low Carbon Economics Tool (LCET). Notice that even under the most optimistic scenario, a substantial portion of electricity generation will come from fossil fuels coal (the gray) and natural gas (the dark blue). You can click on the chart o enlarge it:

I asked Weihl what else he learned from the report.

“We were surprised,” he said, “to see the extent to which aggressive innovation combined with modest policy gives you a kind of triple word score benefit—economic gains, job gains and very significant emission reductions.”

Bill Weihl

He wasn’t trying to say that this is a “free lunch” solution. In the short run, he said, both government and the private sector will need to invest in research and development, and the scaling of newer, cleaner technologies. The government policies embodied in the models either put a price on carbon for the utility industry, which would raise the costs of coal-powered electricity, or they would mandate renewable energy generation for electricity, which would also mean that homeowners and businesses would initially pay more.

“In the short term, there are costs to these policies but they are relatively modest,” Weihl said. “In the longer term, there are significant benefits.”

Washington policymakers are one of the target audiences for the Google study. The company wants to see investment in research.

“If there is one bottom-line recommendation in the short term, for the current budget discussion, it would be, ‘don’t cut R&D,’ ” Weihl told me.

There’s lots more in the report, and Google has made the raw data available on a website that will occupy energy-policy geeks for hours.

Several other findings struck me.

First, reaching tipping points in electric-car battery technology “could be transformative.” Rapid decreases in battery costs and increases in energy density could lead to electric cars and hybrids achieving 90% of new vehicle sales by 90%. This is great news for those who want to reduce America’s depending on oil imported from repressive regimes.

Second, cheap grid-storage creates both significant opportunities and unintended consequences. Grid-scale storage makes it easier to bring large numbers of intermittent, renewable energy sources like solar and wind onto the grid. But, in the short run, if the costs of wind and solar power do not come down, low-cost utility scale storage could actually drive an increase in coal consumption because coal is so cheap.

Third, and this is obvious but worth saying, cheap natural gas could reduce GHG emissions in the short term by replacing coal but it is also likely to slow the deployment of clean energy sources in the long term.

Put simple–and you knew this–getting the change we need, when it comes to energy and climate, isn’t going to be easy.

    DEAR SIR,

    SUBJECT: RUN OF THE OCEAN

    RUN OF THE RIVER CONCEPT IS TURNED INTO RUN OF THE OCEAN

    I HAVE DESIGNED THIS CONCEPT CALLED “RUN OF THE OCEAN”

    AND I HAVE DESIGNED CASCADING MARINE HYDRO POWER

    GENERATION USING THE HYDRAULIC LAWS TO GENERATE GREEN

    ELECTRICITY AND THE APPLICATION IS OCEAN WATER IN MAN

    MADE UNDERGROUND RIVER.

    OCEANS WILL NEVER RUN AND I AM THE ONLY PERSON IN THE

    WORLD TO DESIGN A CONCEPT IN WHICH OCEANS RUN BELOW THE

    MSL IN MAN MADE STRUCTURES.

    METHOD:

    FIRST SELECT A GOOD PLACE FOR DIGGING A UNDERGROUND RIVER

    NEAR THE OCEAN SIDE OR THE WATER BODY

    PLACE A 250 DIAMETER CIRCLE PIPE UNDER A 20 METERS DEEP

    OCEAN

    DIG A 100-METER DEEP AND 250 DIAMETER WELL SLANTINGLY

    SLOPPILY DOWN FROM THE BOTTOM OF 20 METERS DEEP OCEAN

    BED

    THE WELL IS 250 METERS WIDE AND 100 METERS DEEP

    “THE WELL IS NOT 100% VERTICAL” BUT SLIGHTLY SLANTING

    THE WELL WILL COME OUT OF THE BEACH SIDE AND THE DIGGING

    SHOULD BE TOWARDS THE CITY OR THE VILLAGE WHERE PEOPLE

    LIVE.

    THIS WELLS BOTTOM WILL TOUCH –100 (MINUS 100) METERS

    BELOW THE MAIN SEA LEVEL AND UNDER THE EARTH

    AT THE WELLS BOTTOM 10 ATMOSPHERIC PRESSURE IS

    ESTABLISHED NATURALLY BECAUSE THE WELLS INLET IS IN THE

    20 METERS DEEP OCEAN WATER AND THE WATER RUNS DOWN FROM

    THE MAIN SEA LEVEL TO MINUS 100 METERS BELOW THE MAIN SEA

    LEVEL ( 20 METERS DEEP OCEAN WATER + 100 METERS WELL)

    THE WELL IS COMING OUT OF THE BEACH AREA AND THE WELLS

    OUTLET IS ESTABLISHED AT MINUS 100 METERS IN SOLID GROUND

    FROM THE WELLS BOTTOM SIDE A MAN MADE UNDERGROUND

    RIVER IS DUG SLANTINGLY DOWN TO REACH MINUS 450 METERS

    UNDER THE EARTH

    THE TOTAL LENGTH OF THE MAN MADE RIVER IS 40 KILOMETERS

    LONG, 150 METERS WIDE AND 150 METERS DEEP

    THE 250 DIAMETER WELL HAVING 100 METERS DEPTH WILL ACT AS A

    “HYDRAULIC HEAD” FOR THE UNDERGROUND MAN MADE RIVER

    AT THE RIVER INLET 10 ATMOSPHERIC PRESSURE IS ESTABLISHED

    NATURALLY 24 X 7 ALL THE YEAR

    ON THIS SLANTINGLY SLOPPILY DOWN MAN MADE UNDERGROUND

    RIVER 20 INDEPENDENT POWER GENERATION STATIONS ARE

    CONSTRUCTED

    THERE IS A GAP OF 2 KILOMETERS IN BETWEEN TWO INDEPENDENT

    POWER GENERATION STATIONS

    WHEN WATER IS RELEASED FROM THE BOTTOM OF THE WELL AND

    ENTER THE UNDERGROUND RIVER INLET THE RELEASED WATER

    WILL RUN 2 KILOMETERS LONG AND OCCUPY 150 METERS WIDTH

    AND 150 METERS DEPTH

    THIS 2 KILOMETERS LONG MAN MADE UNDERGROUND RIVER IS

    CONVERTED AS A MAN MADE RESERVOIR CALLED THE P1.

    THIS RESERVOIR DIAMENTIONS WILL BE INLET 150 DIAMETERS AND

    OUTLET 40 DIAMETERS AND WILL LOOK LIKE A MISSILE.

    THERE WILL BE 20 INDIPENDENT RESERVOIRS ON THE 40

    KILOMETERS LONG SLANTINGLY SLOPPILY RIVER

    ALL 20 INDEPENDENT RESERVOIRS WILL BE i.e.

    IN METERS ONLY

    PI RESERVOIR: 150 DIAMETERS INLET AND 40 DIAMETERS OUTLET
    P2 RESERVOIR: 150 DIAMEERS INLET AND 40 DIAMETERS OUTLET
    P3 RESERVOIR: 150 DIAMETERS INLET AND 40 DIAMETERS OUTLET
    P4 RESERVOIR: 150 DIAMEERS INLET AND 40 DIAMETERS OUTLET
    P19 RESERVOIR: 150 DIAMETERS INLET AND 40 DIAMETERS OUTLET
    P20 RESERVOIR: 150 DIAMEERS INLET AND 40 DIAMETERS OUTLET

    THE CONCEPT DESIGN IS INLET 150 DIAMETERS AND OUTLET 40

    DIAMETERS. POWER GENERATION IS DONE IN THE PATH OF

    FLOWING WATER COMING OUT OF THE 40 DIAMETER OUTLETS

    WATER WHEN RELEASED FROM 40 DIAMETER OUTLET THE

    RELEASED WATER WILL HAVE A WATER PRESSURE HEAD TO

    IMPINGE EACH TURBINE INDEPENDENTLY.

    KINDLY UNDERSTAND EACH INDEPENDENT RESERVOIR DIMENTIONS

    AND UNDERSTAND THE VELOCITY OF THE RELEASED WATER FROM

    EACH RESERVOIR OUTLET BECAUSE WATER IS RUNNING DOWN AND

    DOWN TO REACH MINUS 450 METERS BELOW THE MAIN SEA LEVEL

    KINDLY NOTE THE OCEAN OR THE WATER BODY WILL BE 450

    METERS ABOVE THE TAIL POND

    WATER IS CONTINOUSLY RUNNING DOWN FROM THE MAIN SEA

    LEVEL TO MINUS 450 METERS THE WATER HAS TO RUN 40

    KILOMEERS AND THE RUNNING WATER IS PASSING

    THROUGH 20 INDEPENDENT POWER HOUSES BEFORE THE WATER IS

    FALL INTO THE TAIL POND SIUATED AT — 450 METERS BELOW MSL

    WATER WILL NEVER RISE ABOVE DESCRIBED DIMENTIONS OF THE

    UNDERGROUND RIVER (FROM BOTTOM OF THE WELL) AND WILL

    NEVER TOUCH THE MAIN SEA LEVEL

    With energy needs rising and ever-growing requirements for cleaner energy sources, our company is dedicated to extracting renewable energy from our environment – cleanly, efficiently, and appropriately. This concept illustrate our creative solutions for green energy generation.

    · there is a significant altitude drop, where the water comes into the “master” reservoir before being distributed to other reservoirs, rushing over a drop of few hundred feet, Operating at the high plant factor of 60% requires durable machines and accurate control equipment. This concept depends on automatic system combinations with SCADA(supervisory control and data acquisition, SCADA systems and software permit them to analyze all these issues, related to capacity, transmission and distribution, and respond effectively to prevailing market conditions in both the wholesale and retail markets.)usages are specifically geared for high usage and profitable operations. The fully automatic station will be trouble-free. All were reviewed on a levelized basis, taking into account capital costs, fuel costs, O&M costs, financing costs etc
    · Both wind and solar have received high levels of government subsidies and incentives. As a result, today’s costs of power from wind and solar are artificially low.

    • Mark, this is an excellent point and I wish I had made it. Predicting is very hard, especially about the future. Could forecasters have anticipated Google in 1995? I think not.
