In April of 2015 at a forum on the British Columbia carbon tax at MIT, I heard Merran Smith of Clean Energy Canada (http://cleanenergycanada.org) say if you add up the GDP of all the individual countries which have some kind of price on carbon, either an emission trading scheme (ETS) or a direct tax, it adds up to 42% of global GDP now and, by the end of 2016 when another five provinces in China come on board, it will be over 50%. (You can hear and see Merran Smith say this at 28:20 into this video of the MIT event at https://www.youtube.com/watch?… ).

Having heard expert after expert say, “We need a price on carbon” in order to address climate change, this struck me. Was Merran Smith correct? Have we already begun to put a price on carbon? Looking a little further, I found a variety of carbon pricing structures – carbon taxes, emissions trading schemes, and even internal prices on carbon from individual businesses.

The World Bank 2015 carbon report advance brief ( http://documents.worldbank.org… ) puts it a little differently than Clean Energy Canada:

“In 2015, about 40 national and over 20 subnational jurisdictions, representing almost a quarter of global greenhouse gas emissions (GHG), are putting a price on carbon…

“The total value of the emissions trading schemes (ETSs) reported in the State and Trends of Carbon Pricing 2014 report was about US$30 billion (US$32 billion to be precise). Despite the repeal of Australia’s Carbon Pricing Mechanism in July 2014, and mainly due to the launch of the Korean ETS and the expansion of GHG emissions coverage in the California and Quebec ETSs, the value of global ETSs as of April 1, 2015 increased slightly to about US$34 billion. In addition, carbon taxes around the world, valued for the first time in this report, are about US$14 billion. Combined, the value of the carbon pricing mechanisms globally in 2015 is estimated to be just under US$50 billion…

“In addition, the adoption of an internal carbon price in business strategies is spreading, even in regions where carbon pricing has not been legislated. Currently, at least 150 companies are using an internal price on carbon. These companies represent diverse sectors, including consumer goods, energy, finance, industry, manufacturing, and utilities.”

Costa Rica has provided all of its electricity from renewables, usually a mix of 68 percent hydro, 15 percent geothermal, and 17% mostly diesel and gas, for the first 100 days of 2015.  The Tico Times reports (http://www.ticotimes.net/2015/04/22/costa-ricas-renewable-energy-streak-is-still-going-but-what-does-that-really-mean)

“The clean energy streak is likely to continue. Last Friday [April 17, 2015] ICE (Costa Rica Electricity Institute)  released a report estimating that 97 percent of the country’s electricity will be produced from renewables this year. This is good news for Costa Rican residents, who will see their electricity prices drop up to 15 percent starting this month.”

In 2016, Costa Rica is a launching a satellite to monitor CO2 across the world tropical belt

(http://www.ticotimes.net/2014/04/22/costa-ricas-first-satellite-to-be-launched-into-space-in-2016)

“…the first Central American satellite, built in Costa Rica, will be launched into space in 2016.  The satellite will collect and relay daily data on carbon dioxide to evaluate the effects of climate change.”

Costa Rica announced in 2009 that it plans to be a carbon neutral country by 2021 and they are following through on that planning.

I was cleaning out my storeroom the other day and came across another recycled solar device that I was fooling with a few years ago.  A one liter clear plastic bottle makes a good hot cap or cloche when you cut the bottom off it.  Plant a seedling, pop the bottomless clear cap over it, and you protect  the seedling from the cold.  It probably adds between 5 and 10 degrees F over the outside temperature by protecting the seedling from the wind and by capturing sunlight in a small, closed space.  My twist on this idea was to find different sizes of clear plastic bottles which could nest one inside the other making a double-glazed hot cap cloche.  A double-glazed hot cap cloche might be able to protect the seedlings even better, keeping that small, closed space even warmer than the outside air.

This afternoon, I planted two tomato seedlings in my garden using this device.  We’ll see whether it works.

Tuesday, March 31 I saw Andreas Kraemer, International Institute for Advanced Sustainability in Pottsdam, founder of the Ecological Institute of Berlin, and currently associated with Duke University, speak at both Harvard and MIT.  His subject was the German Energiewende, energy turnaround, energy tack (as in sailing), or energy transition, and also the title of a book published in 1980 (Energiewende by Von F. Krause, H. Bossel and K. F. Müller-Reissmann) 1980 which described how to power Germany without fossil fuels or nuclear, partially a response to the oil shocks of the 1970s, and probably the beginning of the nuclear phase-out.  Chernobyl in 1986 gave another shove in that direction and continues to do so as Chernobyl is still happening in Germany with radioactive contamination of soils, plants, animals, and Baltic Sea fish.

In 1990 the feedin tariff began but it was not started for solar.  It was originally intended to give displaced hydroelectric capacity in conservative Bavaria a market and a bill was passed in Parliament very quickly, supported by the Conservatives (Blacks) in consensus with the Greens and Reds as they all agreed on incentizing renewable, local energy production through a feedin tariff on utility bills.  Cross party consensus on this issue remains today.  This is not a subsidy but an incentive with the costs paid by the customers. The feedin tariff has a period of 20 years and some have been retired.

Solar began with the 1000 roofs project in 1991-1994.   There are 1.7 million solar roofs now although, currently, Spain and Portugal have faster solar growth rates than Germany. Renewables provide 27% of electricity, have created  80,000-100,000 new jobs directly in the industry, up to 300,000 if indirect jobs are added, and is contributing 40 billion euros per year to the German economy.  By producing energy domestically Germany has built a local industry, increased tax revenue and Social Security payments, and maintained a better balance of trade through import substitution.  During the recession that began in 2008, Germany had more economic stability and was even able to expand the renewable sector because steel for wind turbine towers was available at lower prices and financing was forthcoming.

For the past year, the Cambridge, MA city government has had a Getting to Net Zero Task Force studying the implications of a net zero energy building requirement.  They  finished the draft report on March 16, 2015 and will have an open forum to introduce the study to the public on Wednesday, April 8.

The Task Force defined net zero as “an annual balance of zero greenhouse gas emissions from building operations citywide, achieved through improved energy efficiency and carbon-free energy production,” applying it to the net zero target at the community level (citywide).

Net zero new construction (at the building level as opposed to citywide) is defined as “developments that achieve net zero emissions from their operations, through energy efficient design, onsite renewable energy, renewable energy infrastructure such as district energy, and, if appropriate, the limited purchase of RECs [Renewable Energy Credits] and GHG [Greenhouse Gas] offsets.”

The objectives for the proposed actions from 2015 to 2035 and beyond include

(a)  …target of Net Zero Emissions for new construction: New buildings should achieve net zero beginning in 2020, starting with municipal buildings and phasing in the requirement for other building types between 2022-2030.

(b)  targeted improvements to existing buildings: The Building Energy Use and Disclosure Ordinance (BEUDO) will provide the information necessary to target energy retrofit activity, including, over the long term, the regulation of energy efficiency retrofits at time of renovation and/or sale of property.

(c)  proliferation of renewable energy: Increase renewable energy generation, beginning with requiring solar-ready new construction and support for community solar projects, evolving to a minimum requirement for onsite renewable energy generation.

(d)  coordinated communications and engagement: Support from residents and key stakeholders is imperative to the success of the initiative.

On Friday 11/14/14, Ranganayakulu Bodavula Ph D, Chairman and Managing Director of Thrive® Solar Energy Pvt Ltd (http://www.thriveenergy.co.in), spoke at Harvard’s Center for Population Studies (http://www.hsph.harvard.edu/population-development/).  On Monday 11/17/14, he spoke to the MIT student group, e4Dev [Energy for Development] (http://e4dev.tumblr.com).  

Thrive Solar Energy Pvt Ltd is a leading solar powered LED lighting solutions provider from India, offering

“14 types of solar powered LED lights that cater to the lighting needs of children, women, households and villages. Its lights are used by tea estate workers, farmers, weavers, vendors, dairy and any other village level vocation that is in need of a clean, safe and reliable light. Thrive Solar partners with NGOs, women Self Help Groups (SHGs), Micro Finance Institutions (MFIs), funding agencies, banks, donors, educational institutions and businesses to promote and distribute its lighting products to bottom of the pyramid (BOP) communities, located in off-grid and intermittently grid connected geographies.”

Thrive is making 2 million lights per year at a price as low as $2 per lamp and are projecting 4 million per year production soon.  They do not sell directly to consumers but through the different agencies with which they work.  Nearly half of India still uses 12 lumen candles and 40 lumen kerosene lamps which can be replaced with 60 lumen solar lights.  Currently, the Indian government subsidizes kerosene and paraffin prices by $6 billion per year.  Thrive says it can provide solar lights to every Indian family now for about $1 billion.
