Synergy Between Solar and Batteries

Thursday, May 15th, 2014

If storage can be paid for by grid stabilization services, demand charge reduction, etc., then we can have emergency power at supermarkets, restaurants, food distribution centers, gas stations, police stations, hotels, YMCAs, etc. in every town… for little or no additional cost.

Great thing!

NJFREE discusses renewable energy transition ideas at legislative stakeholders meeting in Trenton NJ

Tuesday, May 6th, 2014

Members of NJFREE met with other stakeholders to emphatically make the point that we need a renewable energy transition in New Jersey.  Key elements include:

a requirement of 80% of electricity generation by 2050 from renewable, non-polluting sources like solar and wind;

specific and measurable milestone requirements that will get us to the final requirement;

keeping the definition of renewable energy, non-polluting definition to sources that are truly renewable and non-polluting (not just less dirty fossil fuels for example).

Electric Energy Storage for Solar and Wind: Rapid progress in new technologies, commercial products, and new business models

Thursday, May 1st, 2014

In a hybrid PV/battery storage project in Denville/Hackettstown, NJ, stateoftheart lithium ion batteries work with a commercial PV system, simultaneously generating PV power, providing frequency regulation for PJM, and providing emergency power capability.

No government involvement, no grants…the revenue from the frequency regulation services not only paid for the additional cost of the batteries, but paid for the inverter, too, actually reducing the cost of the system.

US Supreme Court upholds EPA’s Cross-State Air Pollution rule which protects downwind states from power plant emissions

Tuesday, April 29th, 2014

On April 29, 2014, the Supreme Court upheld the U.S. EPA’s Cross-State Air Pollution Rule, a clean air standard that requires 28 states in the East, Midwest, and South to cut emissions of pollutants from coal-fired power plants that cross state lines and degrade air quality in downwind states.

The American Lung Association said: “Millions of Americans will breathe easier, thanks to the decision today by the U.S. Supreme Court that will finally curtail second-hand smog – ozone smog and particle pollution blown across state borders far from their sources, threatening lives and health.”

The Environmental Defense Fund said: “The Supreme Court’s decision means that our nation can take the necessary steps to ensure healthier and longer lives for the 240 million Americans at risk from power plant smokestack pollution near and far.” 

Isn’t it time that we begin restructuring how we generate our electric power, and start transitioning to a renewable energy future?

Emergency Power – think solar!

Sunday, March 30th, 2014

New business models and grid management models can pay for the emergency power capacity –today.

This will only get easier and cheaper as technology progresses.

During SuperStorm Sandy, we learned that we need distributed emergency power for both traditional and new needs:  

  • Traditional: water pumping, sewage treatment, communications infrastructure, emergency shelters, fire & police, etc.
  • New: Supermarkets, restaurants, food distribution centers, gas stations, etc — highly distributed.

Secret fracking chemicals

Friday, February 28th, 2014

Why are gas companies able to get away with failing to disclose what they are injecting into the ground as part of the fracking process?  Currently, companies do not disclose all the fluids they use, and are not required to do so by law. 

Gas companies inject chemicals into the ground to extract gas and later often pump contaminated water back into the ground after the extraction is done, so that they do not have to pay to properly treat the water. 

Polluted water can make its way into drinking wells and public water bodies.  While the discharge of hazardous chemicals is ordinarily against the law, pro-gas groups have gotten exemptions written into the law. 

Do you or your family want to risk getting cancer from drinking polluted ground water?  Are you OK if your property value is diminished if you find out you now live near a toxic waste site?

Companies that make profits off extracting natural resources should have to disclose ALL the chemicals they use. 

Why expose yourself to all those chemicals?  If you start thinking about it, you may well start asking yourself “isn’t it time for a renewable energy transition?” 

Perry Ohio nuclear power plant leaking radioactive water:

Tuesday, January 21st, 2014

The Perry Ohio nuclear power plant is leaking tritium, a radioactive form of water. The radioactive water has been found in groundwater at concentrations more than twice the federal drinking water limit outside of a building where the leak was discovered Monday. 

Thinking about dirty fuels made me recall a bumper sticker that said something like, “When there’s too much solar it’s just called a sunny day.”  Isn’t it time for a renewable energy transition?

Fukushima Disaster: three years later, reactor still white hot and leaking radioactive water

Tuesday, December 31st, 2013

Three years after the disaster, the ruptured core of the nuclear reactor is still giving off roughly one million watts worth of heat, according to Fairewinds Energy, a nuclear safety advocacy group based in Burlington, Vermont.  Soils in the surrounding area, and may food crops grown in Japan, have been poisoned with nuclear contamination.  And radioactive water continues to leak out from the crippled nuclear plant.  Can you believe that supporters still sometime trumpet nuclear as “clean power?!”

A lesson of SuperStorm Sandy: Go solar!

Sunday, December 1st, 2013

The fragility of the electric grid was highlighted.  Solar, by providing energy generation at many places around the state (e.g. right on the roof top of your house or business) means you are not at the whim of the grid. 

The cost of climate change, is being felt now, not in the future.  Large storms like SuperStorm Sandy drive home the point that we cannot sit back and let the future happen to us: we must plan now for our future, and in terms of electricity generation this means a renewable energy transition now.

There are many advantages of distributed generation.  Distributed generation strengthens our electric system and provides greater reliability, especially during natural disasters.

High‐Penetration Renewable Energy in Europe – It’s Already Happening

Tuesday, October 15th, 2013

The Nordic countries –Denmark, Sweden, Norway, Finland, and Iceland –as a group exceeded 63% renewable power in 2012.

Germany’s “Renewable Energy Transformation” requires 80% renewable electricity by 2050. It is ahead of schedule, surpassing 26% in the first half of 2012. The RE Transformation has produced over 370,000 jobs; the German economic research institutes say it has been a net benefit to the economy, and the country’s economy is by far the strongest in Europe (world’s 4th largest economy overall, and the largest exporter).

Most European Union countries have ambitious, binding RE targets. HighPenetration PV in New Jersey and Germany.

New Jersey leads the U.S. in PV penetration. Currently PV penetration is: ~ 4.5% peak generating capacity ~ 1.5% annual energy.

Germany leads the world. German power snapshot: German power: 80 GW peak load and 36 GW min. load 32 GW solar and 30 GW wind generating capacity Solar has on occasion reached 50% of the country’s total load Renewable electricity reached 26% in first half 2012.

Note: A solar power system in New Jersey produces 38% more power than the same system would in Germany!

New Jersey can – and should — establish a requirement of 80% renewable electricity by 2050.
