12 Predictions for 2013

Clarity Moving Beyond the Past


Tarot Deck | 6 of Swords
 ~ The best part of 2013 is that there won't be a federal election. Consequently, some useful things will get done. There will still be way too much partisan malarkey for my tastes, but the electorate expects action on a host of things and the political dynamic will allow more progress than last year's gridlocked, posturing debacle.

My 2012 Predictions Revisited

About 3/4 Accurate


Tarot Deck | 5 of Wands
 ~ So how good was my prognostication of the past year? Not bad, although I did make some creampuff predictions that boosted the grade. Using a scale of 1 (utterly wrong) to 10 (perfectly prescient):

Coal and Wind

Blackouts in India


Map showing India power outage
 ~ As much as 10% of the world's population is without electricity following the second massive grid outage in India this week.

Blame is being spread around among an outdated, rickety grid, a lack of generation capacity, government inefficiency and corruption, a failure to follow agreed-to consumption limits by various states, poor energy pricing that encourages wasteful consumption, and, as one routinely expects from the corporate cheer-leading quarter, supposedly strangling environmental regulations. All of these are true at least in part, but the bigger cause is a failure to plan and build a stronger commitment to renewable energy.

A Renewable Energy Future

80% By 2050


Renewable energy technologies
 ~ A new study by the National Renewable Energy Lab (NREL) shows that the future of electrical energy could be composed primarily from renewable technologies. Is it really possible?

It's not the first such study. Several others have come to similar conclusions. The NREL study adds further rigor and detail to the argument and makes a straightforward statement:
Renewable electricity generation from technologies that are commercially available today, in combination with a more flexible electric system, is more than adequate to supply 80% of total U.S. electricity generation in 2050 while meeting electricity demand on an hourly basis in every region of the country.

The Job Creators—IV

By Industry


 ~ Public transit just makes sense in so many ways.

Jobs created per million dollars of investment

Oh, and where is Big Oil which the API keeps telling us is such a wonderful job creator? The original study suggests combined oil and gas is 5.18 jobs per $1M investment, but that is, well, all gas. If oil were broken out in this chart, their number would be negative. The oil industry has been shedding jobs for years and pales as a job creator to the renewable energy industry.

Others of interest: roads and bridges repair (20), conservation (20), water infrastructure (20), school buildings (19), financial industry (7), nuclear industry (4). Study details here.

16 Predictions for 2012

Continued Conflict


Tarot Deck | 5 of Wands
 ~ 2012 is going to be rather similar to 2011 politically, but there will be some changes on the economic front.

It's an election year, and, although it seems like the election started a year ago (right after the last one ended), this cycle will see yet higher levels of obsession with the election by politicians, journalists, pundits, and, hence, everyone. So, in government, there will be even fewer policy accomplishments than in 2011 (is that even possible?) and science, reason, and critical thinking will be marginalized to the point of invisibility.

The election will change a number of the players, but regrettably will change none of the political dynamic. The dysfunction will continue, public anger and disgust will increase, and only economic downdrafts in Europe and Asia will prevent precipitous erosion in America's global competitiveness.

My 2011 Predictions Revisited

About 2/3 Accurate


The Tarot | The Tower
 ~ A year ago I took a stab at predictions for 2011. Seems like I've run out of time waiting for most of them to come to pass, so it's time for a report card, using a scale of 1 (utterly wrong) to 10 (perfectly prescient):

Electricity in the Developing World

Small Scale, Local Generation


Satellite view of Africa at night
 ~ The need for electricity throughout the developing world is immense and will continue to grow. Unlike in the industrialized countries, much of the developing world does not have large centralized power plants and transmission lines to carry that power to widely-spread users. Nor are they likely to ever have such a system:
Building out the power grid can be prohibitively expensive, which is why in many countries, like Haiti, less than three quarters of the population have grid access. Pike Research’s Clint Wheelock says just for the transmission portion alone it can cost at least $500,000 per mile. And that’s without the distribution portion and any kind of the grid intelligence (smart grid) that is getting all of the investment this year.

Wind Up

FERC Sides with Wind Farms Over BPA


Wind turbines integrated with hydro in Quebec
 ~ How much do we need a smart grid?

Last week the Federal Energy Regulatory Commission (FERC) ruled that the Bonneville Power Administration (BPA) cannot use its monopoly power to force wind farm operators to curtail generation, an action the BPA took in response to a surfeit of hydro power this past spring.

At the time, BPA claimed that they had to curtail wind generation to protect salmon populations. Wind producers argued that BPA should have continued to buy all their generation and could have sold the power elsewhere. BPA's decision cost them both crucial revenue and the production tax credits on which their financing, and hence, the overall project viability, depended.

FERC has now largely agreed with the wind farm operators that BPA could have sent the power to California and instead curtailed generation there.
Wind farm owners, including independent developers and utilities who own their own projects, say the problem is about money, not too much electricity.

"The agency has painted this issue as being about fish and physics," said Stefan Bird, senior vice president at PacifiCorp Energy. "It's about discrimination and dollars."

A Steady Wind

Firmer When Further Flung


Wind variability is ssmoothed by aggregating individual sites
~ As many have long suspected, variable renewable energy sources, like wind, can be made more firm through numbers. Adding enough wind turbines and spreading them geographically smooths out the variability of individual wind turbines.
The impact is significant, and the optimized system varies from 15 to 50 percent of capacity, compared to individual turbine variability that's twice as large. Over a longer period (a year), the optimized (combined) system provides significantly more reliable power to the electric grid. It reduces periods of zero output to a few hours per year, effectively zero probability.
Still, it always comes back to the grid. If we cannot reallocate distributed generation from where it is available to where the load is, none of this matters. A better grid is what will truly unlock the promise of renewable energy.

Energy Lies—II

"Gulf of Mexico Oil Drilling Stymied by Regulation"


Cartoon of oil company profits held up by subsidies
~ Hardly a day goes by without some lobbyist or cash-captured Congressional corpocrat griping about the urgency and importance of greatly increased offshore oil drilling and the supposedly onerous and unnecessary regulatory burden under which the industry chafes. If only the Obama Administration would get out of the way, so the recurring complaint goes, the industry could boost production, increase royalty revenues to combat the deficit and create jobs:
Onerous regulations, endless layers of red tape, restricted access to critical supplies of domestic energy and a lack of direction from government are only a few of the many examples of artificial barriers that paralyze business and make it difficult for America to grow and prosper.
Is any of it true?

Not much. The criticism of lacking a coherent energy policy and direction hits home, especially in the haphazard and half-hearted support for renewables, but otherwise Big Oil and its shills are largely getting away with doing as they please, same as always. Yeah, they doth protest too much.

Too Much Wind Power

What If We Had More Than We Could Use?



Our overly damp spring weather has provided an abundance of hydropower. There's so much that the creaky and antiquated electrical grid cannot take all the power wind turbines are now poised to generate. So the Bonneville Power Administration (BPA) which manages the grid, is shutting down wind turbines. If the turbines don't operate, they don't produce the power that in turn generates the income that pays for their financing.

Thus, wind is made less feasible because of a surfeit of hydro.

Distributed Generation

Using Globally, Generating Locally


Undershot waterwheel on small creek
~ In the developed parts of the world we are all quite familiar with centralized electricity generation. Megawatts of high-voltage electrical power are created by large coal, gas, nuclear, or other installations and sent over the transmission grid to areas of large demand where it is transformed to lower voltage and distributed to individual homes and businesses.

The alternative is distributed or point-of-use energy generation. Water wheels have been used for thousands of years to create mechanical energy for grinding grain, sawing lumber, and pumping water for drinking or irrigation. Windmills have been used similarly. These and other technologies are still in use in much of the developing world today, along with distributed power from less sustainable sources like diesel generators.

16 Predictions for 2011

Looking Forward, Looking Backward


The Tarot | The Tower
It's that time when people make predictions for the coming year.

This is my first try at making a formal list of prognostications, which I plan to revisit a year hence when I make my second list.

Many are about cleantech and renewable energy, or about things that will affect the future of them.

I hope I'm wrong about many of these.

Off-Grid Africa

Distributed Power is Growing All Over

Low-cost, small-scale, simple distributed power generation continues to make gains. It was part of the original business model for the Hydrovolts turbine, the genesis of Clarian Power, and the market power of Nokero light "bulbs."

Now general-purpose solar panels are going up in remote locations around the world, especially Africa, where the sprawling grids of centrally-generated power plants don't reach.

Providing even a small amount of electricity makes an enormous difference in the quality of life for people in the developing world. It provides lighting which allows students to read and study at night, improving education, a key precursor of upward economic mobility. It can replace unhealthful sources of illumination, cooking and heating, especially animal manure, charcoal, and wood, many of which are burned inefficiently and with limited attention to adequate ventilation.

The economics make sense. The cost of charging equipment (particularly cell phones) in both time and direct expense is rapidly recovered by the value of local generation capacity.

The biggest impediment to more distributed generation is the initial capital cost. Traditional lenders prefer large central projects because the due diligence is both familiar and easier--there is only one location to examine, and to subsequently monitor, over the course of the financing. Micro-lending could pick up the slack, but there still needs to be a business model that creates revenue to pay back the investment. While selling a goat may work for some, providing a local charging station may work for others. As remote villages gain dribs of electricity, however, more models will arise. Entrepreneurs exist in rural Africa too, and having a enabling platform technology like electricity opens the way to many kinds of businesses. As costs of solar panels continue to decline, and as other forms of distributed generation become available, the effect on rural areas of the developing world will be transformative.

Myth, Legend and Reality

Are Electric Cars for Real?

220V at home is all most need.
Cars easily charge overnight.
Are electric cars a false promise or a panacea? Actually neither, but myths get in the way of understanding the role that they can and must play in solving our future transportation needs. These myths include:

1. Electric Cars Are Glorified Golf Carts

90% of my driving is between my house and one of three close-by park-and-rides. For most of my needs a glorified golf cart would serve very nicely. However, electric vehicles are increasingly indistinguishable from their fossil-fueled brethren on styling, performance, creature comfort, safety and reliability.

Crashing the Grid

Map of US electrical grid
The US Electrical Grid. Click for interactive version
We know the electrical grid is an ad hoc assemblage figuratively bound together with bubblegum and baling wire. According to Ontario Hydro, the massive utility in Canada's most populous province, it is destined to break in the face of new technology:
The energy chief of demand-response power utility Toronto Hydro Anthony Haines has warned if ten per cent of households in its service territory within Canada adopted electric vehicles it would crash the electricity grid, according to reports.

The company said electric cars consume around triple the amount of energy that is usually used in the average home, with the extra charging load at peak after-work hours, news service the star.com reported.
As the story suggest, this Chicken Little act may only be intended to grease a rate increase. While politics has a role, government is sceptical. Nonetheless, upward pressure on rates is rampant.
