At “How Cities and Companies Can Work Together to Operate in the New Energy-Constrained Economy” a panel discussion (press release), Bruce Katz, Vice President and Director of the Metropolitan Policy Program, Brookings Institution, said “2.7 million new jobs” will be created in moving to the clean energy / low carbon economy.

Mr. Katz also noted that two out of three Americans – 200 million people – live in the 100 biggest metropolitan areas, and those 200 million people are responsible for 75% of our GDP. High carbon energy is no longer cheap. The people in those metropolitan areas, and elsewhere, therefore, must act. Continue reading

Indian Point 1 – A Zombie Nuclear Power Plant

Follow LJF97 on Twitter Tweet

Bucolic?  Pastoral? Looks that way, but looks can be deceiving.  First of all, there’s Indian Point 1. Then there’s the water issue.  Other issues are waste and national security.

Indian Point 1

  • Brought online in August, 1962.
  • Shutdown in October, 1974.
  • Spent fuel is stored on site.
  • Scheduled to be closed in 2026.
  • Operated 13 years.
  • “Zombie” 52 years.

Talk about externalities! “Zombie” since ’74 and scheduled as such for another 25 years, total of 52 years. NRC.  What does it cost to maintain and manage as a “zombie?” And who pays? The owners or the taxpayers?  And did the plant produce so much power in the 12 years of operation that it will make a profit after 52 years of being managed and serviced?

Indian Point 2

  • Rated Thermal Power: 3216 MW
  • Net Electrical Rating: 1032 MW
  • Water Requirements: 840,000 gallons per minute

Indian Point 3

  • Rated Thermal Power: 3188 MW
  • Net Electrical Rating: 1051MW
  • Water Requirements: 840,000 gallons per minute

Summary – Indian Point is a 2.083 GW complex. Replacing it with new nuclear would cost about $12 to $18 billion, plus the cost of fuel, security, and the costs of interest during the 8 to 10 years of construction. Replacing it with solar would require about 2 million PV solar panels, at a cost of $8 to $12 billion, or 570 wind turbines at a cost of $4 to $6 billion. 2.0 gw of wind and solar do not require 1,680,000 gallons per minute of cooling water, or even 1.0 gallons per minute. Solar and wind do not require fuel and do not produce waste. Nor do they present national security challenges.

The Newark Star Ledger reported (here and here) that Public Service Electric and Gas, PSE&G, a subsidiary of Public Service Enterprise Group, PSEG, is installing a  2,700-ton chiller the University of Medicine and Dentristy of New Jersey, UMDNJ. This an $11.4 million investment in negawatts. The Star Ledger reported that UMDNJ will save $1.3 million per year on energy costs.What’s the payback? An $11.4 million investment will save $1.3 million per year. That means the system will pay for itself within 9 years, assuming the price of energy remains constant.  I think it’s a much more reasonable to assume that the price of energy will go up, so the payback will be higher and the system will pay for itself sooner.

The system will work long after it is paid for. It will save $13 Million over the next 10 years and $26 Million over the next 20 years – assuming electricity costs are constant.  Assuming electricity costs increase an average of 5% per year, this will save $16.35 Million over the next 10 years, and $42.99 over the next 20 years.

  • Projected Savings of $11.4 Million investment.
  • After 1 Year: $1.3 Million, a return on investment of 11.4% in one year.
  • After 5 Years: Save $7.18 Million, for a total ROI of 63%, assuming a 5% annual increases in cost of energy.
  • After 10 Years:  Save $16.35 M; total ROI of 143.4%).
  • After 15 Years: Save $28.05 M; total ROI of (246%)
  • After 20 Years: Save $42.99 M; total ROI of 377%).

21 Century Energy or Business As Usual?

NY Times Special (Business As Usual) Energy Section

Clifford Krauss’ “Can We Do Without the Mideast?”
sets the tone for the “Special Energy Section” in the NY Times, March 31, 2011. “The path to independence – or at least an end to dependence on the Mideast – could well be dirty, expensive and politically explosive.” Is this an April Fool’s Day joke?

It will be better for the economy, better for the environment, and better for ourselves, our children, and our grandchildren. Continue reading

Nuclear Power and Cocaine

Asking a nuclear engineering professor “Is radiation bad?” is like asking Charlie Sheen “Is cocaine bad?”

On “Morning Edition” today, 3/30/11, Renee Montagne did just that when she interviewed Professor Peter Caracappa, a member of the faculty of the nuclear engineering department of RPI (Interview / nuclear engineering at RPI). As is typically the case, what was left out of the conversation could have been more interesting than what was in the conversation. My questions for Professor Caracappa are below: Continue reading

New Solar Tech: Less Waste; Lower Cost.

Waste Equals Cost. Less Waste Equals Equals Lower Costs.

1366 Technologies - Standard 4-step, high waste process versus 1366 Direct Wafer process

Standard process versus 1366 Direct Wafer process

 

 

People frequently ask me about waste in Solar PV. Clearly, given that no fuel is consumed, no waste is produced from the use of a solar energy system to generate electricity. PV solar modules are not flammable (below something like around 1,000o C) so even if the building burns down under the modules – which could produce toxics – there is no waste from the solar energy system.

However, there is a carbon footprint in transport and installation, and there is waste associated with the production of solar modules. This is about to be reduced. Continue reading

Cats, Mice, and Sustainable Energy

“Join me in setting a new goal:  By 2035, 80 percent of America’s electricity will come from clean energy sources.”  – President Barack Obama, State of the Union, January 25, 2011.

When a mouse makes noise, only other mice and local cats take notice. When a lion roars, however, everyone notices; other lions, elephants, zebras, gazelles, smaller cats, mice ….

New Jersey is one of 27 states, which, like the District of Columbia, have a Renewable Portfolio Standard, or RPS, mandating that by a certain date, a specific target of a renewable energy capacity will be deployed. An additional five states have non-binding goals. (This are listed by the U. S. Dept. of Energy at Energy Efficiency and Renewable Energy.)

In New Jersey the RPS is 22.5%, about 1.6 gigawatts (GW), by 2021. New Jersey today, in January, 2011, has about 300 megawatts of renewable energy capacity.  I am confident that New Jersey will meet, and possibly exceed its RPS goal. We started with 9.0 kilowatts (KW) of photovoltaic solar in 2001. We were up to 211 megawatts (MW), by the end of September, 2010, and we added an additional 24 MW in December, 2010. Even when you factor in 30 MW of biomass, 8 mw of wind power, and 1.5 mw of fuel cells, this is less than 20% of the goal of 1.6 gw. (This is shown at the NJ Clean Energy Program Renewable Energy Technologies page.) However paradigm shifts are systems phenomena. They occur at exponential rates.  We went from 9.0 kw in 2001 to 211 mw in mid-2010, to 360 mw  by the end of 2010.  In December, 2010, we added an additional 10% – moving from 236 mw to 260 mw.  We are hitting the handle of the hockey stick.

California’s RPS is 33% by 2030. In Texas, the RPS calls for 5,880 MW by 2015. California , New Jersey and Texas are the roaring mice in domestic US clean energy policy. And a cat – the lion in the Oval Office – the President of the United States – has listened to the mice in California, New Jersey, and Texas. Last night he roared.

In his “State of the Union” address, January 25, 2011, President Obama set a lofty goal: “80% clean electric generation by 2035.” While I think we can do better – 100% clean renewable sustainable energy by 2025 – Obama’s goal is specific, measurable, achievable, realistic, and time-bound. It’s SMART. It’s also wise.

As a President should, Obama is thinking, and thinking long term.  We at Popular Logistics wish him success because success for a President means a better future for the nation.

Two observations.

  1. There is no such thing as “Clean Coal.” Even if we capture and sequester all the carbon dioxide produced from burning coal, which is expensive, there are still impurities, such as arsenic, lead, mercury, uranium, zinc in coal. And mining and processing coal is a very dirty business.
  2. Nuclear is heavily regulated. We exercise tighter control over the wastes. In practice, nuclear power is arguably cleaner than coal. But in reality, things happen.

One question is “Can we achieve Obama’s Clean Electricity Goal?” But a better question is “How can we achieve this goal? ” My back of the envelope response is:

  • 100 gigawatts offshore wind,
  • 100 gigawatts land based wind,
  • 50 gigagwatts solar,
  • 75 gigawatts stored micro-hydro or biofuel, for when the sun isn’t shining and the wind isn’t blowing.

And as Amory Lovins, of the Rocky Mountain Institute, says, “The cheapest unit of energy is the ‘Negawatt’ – the energy you don’t have to buy.”  How much can we reduce our energy requirements? How much can we gain by conservation?

Solar Energy Saves Money, Could Provide Free Electricity and CASH to Municipalities & Schools in New Jersey

1.5 MW Solar Array, Rutgers University, Livingston Campus

1.5 MW Solar Array, Rutgers University, Livingston Campus

New Jersey taxpayers could net $36.9 million per year, $369 million over 10 years, with the installation of 152.5 megawatts (MW) of photovoltaic (PV) solar electricity systems on public schools, community colleges, and each of the public universities in the state.

The systems would pay for themselves within the first 8 years. At 2010 values of electricity and Solar Renewable Energy Certificates (SRECs), these systems would generate electricity worth approximately $300 Million and SRECs worth $1.2 Billion over the first 10 years, approximately $369 Million in excess of the cost of the systems, and provide virtually free electricity over the remainder of their 35 to 40 year lifespan.

Widespread deployment of solar energy increases the resilience of the electric grid, strengthens national security and can enhance local emergency response capabilities.

These are the conclusions of a feasibility study by Lawrence J. Furman, principal of Furman Consulting Group, LLC during the course of his studies for an MBA in Managing for Sustainability at Marlboro College Graduate School.

Wind Power and Noise

How Loud Is A Wind Turbine? Our friends at Treehugger re-published this graphic from GE, which builds wind turbines.

Graphic showing wind turbine noise

If a wind turbine spins in a forest do you hear it?

If you’re standing next to a utility scale wind turbine, then you’ll hear it. At 300 meters, which is as close to residences as we can build them, they are about as loud as a refrigerator. People report that a set of wind turbines – they tend to be built in sets – produce noise and subsonic vibrations, which can be irritating. But what should we do? PV solar modules are silent. However, they don’t produce power at night.  Coal produces tons of toxic waste, from arsenic to zinc, including cadmium, mercury, lead, uranium, thorium – actually producing more radioactive waste than nuclear power.  And coal produces carbon dioxide. Mining coal and uranium is dirty. We are converting mountains of natural beauty into mountains of toxic waste. (see Coal Tattoo, or I Love Mountains)

So how loud is a wind turbine? And if wind power is too loud, how should we turn on the lights?

Renewable Energy, The Wall St. Journal, Faux News

George Gilder, writing in the Wall Street Journal, 11/18/10, in California’s Destructive Green Jobs Lobby complained of the defeat of the repeal of the “Global Warming Solutions Act.”

“Economic sanity lost out in what may have been the most important election on Nov. 2—and, no, I’m not talking about the gubernatorial or senate races. … This was the California referendum to repeal Assembly Bill 32, the so-called Global Warming Solutions Act, which ratchets the state’s economy back to 1990 levels of greenhouse gases by 2020. That’s a 30% drop followed by a mandated 80% overall drop by 2050. Together with a $500 billion public-pension overhang, the new energy cap dooms the state to bankruptcy.”

Gilder also wrote: “California officials acknowledged last Thursday that the state faces $20 billion deficits every year from now to 2016.” That’s $120 Billion over the next 6 years. This is a state of 37 million people (US Census). It should be able to borrow that money at 4% or 5% – which is $3083 per capita. Borrowed at 5% interest over 20 years, it’s $20.35 per person per month – which does not seem to be enough to push someone into bankruptcy.

Solar Power and Toxic Waste

If you think there are zero direct emissions from the production of electricity from PV solar modules, YOU’RE ABSOLUTELY CORRECT. There are however, indirect emissions associated with production, transport, installation and refresh / recycle are dependent on the technologies used in those processes. Most are associated with the use of fossil fuels and nuclear power to manufacture and move solar modules.

Three observations stand out David Biello’s article, “Dark Side of Solar Cells Brightens,” Scientific American, Feb. 2008.

  1. Indirect emissions are derived from the fossil fuels used to generate the electricity for PV manufacturing facilities.
  2. Heavy metals, such as cadmium, used to manufacture PV solar modules, can be recovered from mining wastes and coal ash.
  3. Overall toxic emissions are 90 to 300 times lower than those from coal power plants.

Todd Woody/Green Inc. Blog: Samsung Enters Solar Deal in California

Seth Woody reports from the Green Inc. blog at the Times

Samsung, the Japanese conglomerate best known to Americans for its televisions and cellphones, is jumping into the American solar business.

Pacific Gas and Electric, the California utility serving much of the northern and central parts of the state, asked regulators last week to approve a series of 25-year contracts [pdf] for 130 megawatts’ worth of photovoltaic power plants to be built by Solar Project Solutions, a joint venture between Samsung America and ENCO Utility Services, a former subsidiary of the utility company Edison International.

The deal is the latest of a spate of such agreements signed by California utilities as they take advantage of the increasing attractiveness of photovoltaic power as the price of solar modules falls and new competitors enter the market.

Unlike large solar thermal power plants that use mirrors to heat liquids to generate steam to run electricity-generating turbines, photovoltaic farms can be built relatively quickly near cities and existing transmission lines.

Todd Woody,–  Samsung Enters Solar Deal in California,

on the Green Inc. Blog (NYTimes.com)

Mr. Woody’s point about photovoltaic systems is well-taken: here’s another photovoltaic application, the Marine Corps’ recently announced GREENS system:

A year ago, U.S. Marines operating in the Arabian Desert only viewed the sun as the source of the region’s relentless heat. Recently, the Office of Naval Research (ONR) Advanced Power Generation Future Naval Capabilities program introduced technology that allows the Marines to harness some of that sunshine to help power their field equipment.

Fueled by the sun, the Ground Renewable Expeditionary ENergy System (GREENS) is a 300-watt, photovoltaic/battery system that provides continuous power to Marines in the field. ONR began exploring the GREENS idea in fall 2008 in response to a Marine Corps requirement from Iraq for an expeditionary renewable power system.

“It’s vitally important to have power in the battlefield especially these days in an irregular warfare environment,” said Marine Col. Thomas Williams, a senior officer at ONR.
