California, Massachusetts Top Performers in Clean Tech
THE PURSUIT OF RENE WABLE RESOURCES AND ENERGY
efficiency continues in the United States, and states and
cities lead the way toward an energy industry supported by
According to the 2017 U.S. Clean Tech Leadership Index, two
states have maintained their leading position.
The eighth annual report published this spring by clean-
energy analyst Clean Edge Inc., shows California
and Massachusetts holding the top spots again
as they have for several years. California has
held the No. 1 spot all eight years the report
has been published. Massachusetts has been
No. 2 behind California for the last five years.
Rounding out the top 10 in descending order
are Vermont, Oregon, New York, Connecticut,
Colorado, Washington, Minnesota
The Clean Tech Industry Index
tracks activity based on a diverse set
of underlying industry indicators.
It ranks activity for all 50
states and 50 of the largest
The states are weighted
according to their performance
in the categories of technology,
policy and capital. Technology
measures deployment in such
areas as clean energy, clean
transportation and green buildings. Policy
addresses regulations, mandates and incentives.
Capital includes financial as well as human and
For its part, the report notes that California received
more than 27,000 gigawatt-hours (GWh) of utility-scale and
distributed solar power alone in 2016. That’s more than five
times the amount generated in Arizona, the state with the
second-most solar production. California also has more than
1. 2 million registered electric and hybrid vehicles, and it was
the beneficiary of more than $9.5 billion in clean-tech venture
capital in the last three years.
At the metro level, several California cities also top the list.
The top 10 cities are San Francisco; San Jose, Calif.; Washington,
D.C.; San Diego; Portland, Ore.; Los Angeles; Boston; Seattle; Salt
Lake City; and Austin, Texas.
Cities are measured according to their performance in the
categories of green buildings; advanced transportation; climate
and carbon management; and clean-tech investment, innovation
Efficiency, Networks and Renewables Lead Way in Electricity Investment
GLOBAL ENERGY INVESTMENT patterns
are a mixed bag of trends. A recent
snapshot of these patterns offers an
equal measure of good news and cause
The International Energy Agency
(IEA) released “World Energy Investment
2017,” its second annual benchmark
analysis of energy investment, on July
11. The report reveals a sector that is
contracting in some ways but expanding
According to the report, total energy
investment worldwide was around $1.7
trillion in 2016, accounting for about 2. 2
percent of global gross domestic product
(GDP). While still a significant share, in
real terms, this represents a 12 percent
drop from the year before.
Investment in some areas grew
substantially. For example, spending on
energy efficiency and electricity networks
grew by 9 percent and 6 percent,
In 2016, the electricity sector moved
ahead of the fossil-fuel supply sector to
become the largest recipient of energy
investment for the first time. A two-year
drop of 38 percent in capital spending
in the oil and gas sector also allowed
low-carbon industries, such as electricity
networks, to increase their share of the
total supply-side investment to 43 percent
over the same time frame.
Investment in new renewables-based
power capacity remained the largest areas
of electricity spending at $297 billion,
even though the total fell by 3 percent
Technology also is making the energy
sector more productive. Over the past five
years, renewable capacity additions and
expected output increased by 50 percent
and 35 percent, respectively, even while
actual investment dropped by 3 percent.
All this is good news for investors but
not necessarily good news for workers.
For example, the report notes that a
30-percent drop in jobs in U.S. oil and gas
industries was accompanied by only a 6
percent decrease in production.
