Tesla sales in the first 10 months of 2014 were down 16% on a year over year basis compared to 2013.
Everyone is running around talking about how solar PV has hit grid parity in multiple states and countries. Interesting parable - solar - in that solar PV has been around a long time and costs have been coming down significantly for many many years. I worked in a solar PV company back in 1979 and 1981, designing and building irrigation and remote power solutions.
Right now, for solar to be cost effective, even after all of this insane cost reduction, it still needs a 55% subsidy to stand on its own two feet here in Massachusetts. The is a federal incentive of 30%, and a state incentive of another 25% or so (based on variable SREC pricing). Even with these subsidies, it is a hard sell. Certainly much easier with $0.80/watt panels.
Point being is that electrochemical batteries have been around a long long time, and cost improvements have come slowly. We all want to see a sea change in the cost/performance of batteries, and let's support and cheer on the innovators pouring their time and resources into bringing about a better future. I get concerned about the mounting hype cycle and the damage that unrealized expectations may bring.
So, why isn't Elon Musk introducing an electric vehicle that can go 200 miles at the $50,000 or $60,000? Price? Some have postulated that the Tesla Model 3 will actually be priced closer to $60,000 when it is introduced. The introduction date has been publicly stipulated to be 2016, then perhaps 2017.
Based on the 2 year delay with the Model X, it is likely that the Model 3 won't be available to purchase until 2019, as a prototype has not yet …
Assume a more efficient, lighter smaller car than the model S, and a 200 mile range as compared to the Model S 285 mile range. Battery capacity may need to be 50 kWh, and the cost will have to be $200/kWh, compared to $352/kWh on the Model S, a 43% reduction in battery cost. Will we see a 43% reduction in battery cost in the next 5 years? Nope. Will it be close? Yup.
Will people want to buy a car with 200 mile range? It is not going to be a a mainstream product with that kind of range. Five years from now, the ICE and hybrid designs are going to continue to be more efficient, and more difficult to compete against. Battery cars 5 years from now are going to be an important part of the transportation system, but with inferior performance, they will occupy a "big niche" in the market, but will not be mainstream. Ultra hybrids, however, will benefit from the lowering of battery costs and ICE improvements, and will occupy an increasing position in the market.
The economic picture of the United States consumer is not going to change a whole lot in the next five years, sadly. Cars are going to continue to be a smaller share of the transportation pie, with many more options being available, from bike friendly cities, expanded Uber/Lyft, Zip cars, bike sharing, expanded transit, moving to cities, etc. Life choices are already changing, as both of my children in their twenties do not have cars, although the once did.
Most people have limited budgets and will not be able to afford the cost and hassle of having a vehicle with a lower utility value. Given the choice between spending less for a car that can go 450 miles, or spending more for a car that can go 200 miles, the choice for many is what can be called a no brainer, no matter how environmentally just an electric vehicle option may be.

Google Inc. has joined the search for better batteries to power its expansion into consumer electronics and other hardware.
In late 2012, a team led by former Apple Inc. battery expert Dr. Ramesh Bhardwaj began testing batteries developed by others for use in Google devices. About a year later, the group expanded to look at battery technologies that Google might develop itself, according to people familiar with the matter.
The group, part of the Google X research lab, is small, with just four members. A Google spokeswoman declined to comment or to make Dr. Bhardwaj available.
Google in recent years has moved into industries such as transportation, health care, robotics and communications, designing physical devices that require efficient batteries. Chief ExecutiveLarry Page told analysts in 2013 that battery life for mobile devices is a “huge issue” with “real potential to invent new and better experiences.”
Dr. Bhardwaj has told industry executives that Google has at least 20 battery-dependent projects. The company’s latest self-driving car runs on batteries recharged by electricity. The first version of Google’s Glass Internet-connected eyewear suffered from short battery life, which the company hopes to improve. An effort to use nanoparticles to diagnose diseases relies on a small battery-powered monitoring device.
Scientists at Stanford say they’ve created an aluminum-ion battery that solves many of the problems with lithium-ion and alkaline batteries. Is this a miracle breakthrough? WSJ’s Jason Bellini has #TheShortAnswer.
Google joins many technology companies trying to improve batteries, including Apple,Tesla Motors Inc. andInternational Business Machines Corp. These efforts have so far produced only incremental gains, a contrast for tech companies accustomed to regular, dramatic leaps in the efficiency of semiconductors.“Google wants to control more of their own destiny in various places along the hardware supply chain,” said Lior Susan, head of hardware strategy at venture-capital firm Formation 8. “Their moves into drones, cars and other hardware all require better batteries.”
Emerging battery technologies promise bigger gains. Solid-state, thin-film batteries transmit a current across a solid, rather than liquid, making them smaller and safer. Such batteries can be produced in thin, flexible layers, useful for small mobile devices. But it isn’t clear whether they can be mass produced cheaply, said Venkat Srinivasan, a researcher at Lawrence Berkeley National Lab.
At Google, Dr. Bhardwaj’s group is trying to advance current lithium-ion technology and the cutting-edge solid-state batteries for consumer devices, such as Glass and Google’s glucose-measuring contact lens, according to the people familiar with the matter.
In a February presentation to an industry conference, Dr. Bhardwaj described how solid-state, thin-film batteries could be used in smartphones and other mobile devices that are thinner, bendable, wearable and even implantable in the human body.
For a wearable device like Glass, he said, the batteries could help power energy-intensive features like video. For the contact lens, the technology is safer because it doesn’t use flammable electrolyte liquid, Dr. Bhardwaj’s presentation explained.
Other teams at Google are working with Chicago-based AllCell Technologies LLC on more potent batteries for four hardware projects, including Project Loon, the company’s effort to beam Internet signals from high-altitude balloons, people familiar with the matter said.
A Project Loon video from late 2013 shows Google engineers bundling AllCell batteries into the system’s power pack. Lithium-ion batteries perform poorly in the subfreezing temperatures of the stratosphere, where Loon balloons float. AllCell wraps lithium-ion batteries in a wax and graphite material that quickly absorbs heat and spreads it evenly, extending their life. Google is experimenting with specially formulated materials for better cold-temperature performance, Jim Morash, a Project Loon engineer said in the video.

Impact of High Solar Adoption on Utility Economics
Impact of high solar market adoption by residential customers on utility economics is illustrated in the infographic below. As solar adoption increases, fixed transmission and distribution costs are spread over fewer kWh sales, increasing electric rates. As electric rates increase, solar payback gets lower and lower, further accelerating the adoption of solar, distributed generation and efficiency.

Jevon's Paradox
In 1866, Stanley Jevons wrote about the seemingly contradictory determination that increased efficiency results in increased consumption: "It is wholly a confusion of ideas to suppose that the economical use of fuel is equivalent to a diminished consumption. The very contrary is the truth. As a rule, new modes of economy will lead to an increase of consumption."
It is now referred to as Jevon's Paradox. A copy of Stanley's book can be accessed here: Jevon's Paradox

Innovation Powering Up India
1.5 Billion People in the World do not have Electricity
India is Deploying Renewable MicroGrids to Close the Gap
December 7, 2014
Author:
Donald S. Bradshaw, Jr., President, Velerity
An innovative hybrid solar-biomass DG power plant in India
is bringing electricity for the first time to villages in the Indian state of
Bihar. Another innovative design, a
biomass gasifier running on rice husks, has been deployed in 85 locations across
Bihar. According to an International
Energy Agency study, approximately 579.1 million people do not have access to
electricity in India. [1] According to a study published by the Vasudha
Institute in India, “…close to 100,000 villages remain un-electrified, with
over 45% of the population having no access to electricity.” [2] Based on the results of the 2011 Census, out
of 246.7 households in India, 32.8% of households, or 80.9 million households,
did not have access to electric light. [3]
There is a strong link, both empirically and statistically,
between access to energy and economic well-being, as seen in the following
chart. According to a recent report,
Rural Electrification in India, having access to reliable electricity
“…represents a key driver behind economic development and raising basic
standards of living.” [4] On average, increasing per capita GDP by $10
requires approximately a 93,000 Btu increase in primary energy
consumption. In the data below, Indian
primary energy use is 20 million Btu per person per year, and per capita GDP is
$1,055 per year. [5]
Electrification in India brings significant benefits to agrarian
economies, increasing irrigation and crop production. It has also been shown that bringing
electrifying households can reduce a household’s expenditures, when switching
from kerosene lighting to electric lighting.
One of the States in India with the lowest penetration of
electricity for household lighting is Bihar, with only 16.4% of its households
reporting electric lighting in the 2011 Census.
This corresponds to 15.8 million households in Bihar which do not have
electricity, out of a total of 18.9 million households.
Being connected to the grid, however, does not guarantee
having access to electricity. Once a village
in India has connected to the grid, generation capacity in India is inadequate
to meet demand. There are four main
reasons why supply does not meet demand.
The first is inadequate installed supply. Economic growth in India in recent years has
outstripped the ability to add additional power plants. The government of India estimates in 2014
that there is a daily shortage of capacity in the country of 30,000 MW. This results in power rationing through
planned outages. [6] A second major factor is breakdowns and
maintenance schedules of existing power plants, forcing plants to be off line even
though power is required. The third
reason is the lack of available capacity in the distribution and transmission
lines to transport the power. The fourth
reason is the lack of revenues due to subsidization, customers not making
payments, and the stealing of power.
According to the World Bank, “In India electricity theft leads
to annual losses estimated at US$4.5 billion, about 1.5 percent of GDP.[7] According to the World Bank, annual losses
by the power sector are expected to reach $27 billion per year by 2017. Between 2007 and 2012, India installed 50 GW
of new generation capacity, which fell short of the original goal of 78 GW.
Planned outages typically occur during times of peak demand,
which is in the evening hours. Outages can
last from 2 to 20 hours per day.
There are many solutions being implemented to address India’s
power situation. For villages that have
no power, solutions include:
The plant has been given the designation SCOPE BIG, which
stands for Scalable CSP Optimized Power Plant Engineered with Biomass Integrated Gasification. It is designed to be demonstration project
for which additional larger scale deployments will follow.
Participants in the project include Indian-based CSTEP
(Center for the Study of Science Technology and Policy, Thermax, the Bihar
State Power Generation Company, Energy Centre of the Netherlands, and the
National Centre for Scientific Research, based in France. Fraunhofer Germany is also participating.
Another innovative approach being taken to address energy and poverty issues in Bihar is Husk Power Systems, which has deployed approximately 85 off-grid biomass
gasification plants in India with agreements in place to deploy additional systems on the African
continent. In 2012-2013, India produced
an estimated record crop of rice, amounting to 104.4 million tonnes. [8] As a by-product of rice production, this
means that India also produced an estimated 25.1 million tonnes of rice husks. [9] For the most part it has been determined that
these rice husks are disposed of in landfills.
After evaluating several alternative approaches, the founder of Husk Power Systems,Gyanesh Pandey, developed
a gasification system that utilizes waste rice hulls as feed stock. The system is comprised of a rice husk
gasifier, a series of filters to clean up the gas, a gas engine, a 35 kW
generator, and a 240 Volt Alternating Current system to connect customers
within a two kilometer distance from the plant.
Within several months of an installation, the company usually has a 75%
market penetration rate. The average
number of customers per system is between 200 to 250 households and additional
commercial customers. Each residential customer
receives two 15 watt compact fluorescent light bulbs and a phone charger. Each customer pays about $2.20 per month for
the service, which reduces their Kerosene use by about 6 to 7 litres per
months, with a net saving per household of an estimated $4.40 per month. Customers can have increased levels of
service, if desired. [10]
The system needs about 110 pounds of
corn husks per hour to operate at full output.
There are many innovations that have been deployed to drive
costs down and make the system successful.
One of the interesting outcomes is that the bulk of the payments that
customers make for their electricity is recycled back into the local economies,
for labor and biomass. More information can

Salem MA Natural Gas Plant Approved with Expiration Date
FROM THE NEW YORK TIMES
Source: http://www.nytimes.com/2014/02/21/business/energy-environment/massachusetts-approves-a-gas-power-plant-with-an-expiration-date.html?hpw&rref=science
In a hearing in Boston, a state siting board voted 5 to 0 to accept a proposal by a major New England environmental group and a company that wants to build the plant that would allow the plant to open, but require it to emit less and less carbon dioxide until it closed by 2050.For years, proponents of natural gas, including President Obama, have promoted it as a “bridge fuel,” cleaner than coal but not clean enough to solve the climate problem. On Thursday, regulators in Massachusetts, in an unusual vote, put that theory into practice when it approved a new gas-fired power plant with only a limited life span.
The Conservation Law Foundation and Footprint Power reached an agreement over a proposed $800 million plant to be built in Salem Harbor, at the site of a coal plant that will shut this year. The new plant would generate 630 megawatts — although in later years, it would either have to limit its hours of operation, install carbon capture or make investments in renewable energy to stay under the declining emissions cap.
The agreement for progressively lower output and a definite retirement date is a first, according to Jonathan Peress, a vice president of the Conservation Law Foundation. Gas cuts carbon dioxide emissions by about half compared to coal, but it is still far too high in carbon to meet the ultimate climate emissions requirements, he said.
“We want gas to continue to displace coal,” he said. “We just don’t want to worry that we’re going from heroin to methadone.”
The agreement was submitted to the Massachusetts Energy Facilities Siting Board this week.
The plant is scheduled to open in 2016 and would operate normally until 2026, when progressively stricter limits would be imposed. In 2049, its last year of operation, its limit would be about one-quarter what it was in 2016.
Joining in the agreement was a state agency, the Executive Office of Energy and Environmental Affairs, which promised that if the deal was approved, it would be written into the state-issued operating permit for the plant. The state would embark on a program to reduce leaks of unburned natural gas. Methane, the main ingredient of natural gas, is a potent global warming gas.
