A Quiet Clean Energy Revolution

March 5, 2019 By EarthWise Leave a Comment

While the Trump administration seeks to prop up and promote use of fossil fuels, the country continues to move in the opposite direction.  Last year was actually a pretty positive year for clean energy in the U.S.

In terms of public opinion, 70% of Americans surveyed believe the country should produce 100% of its electricity from renewable energy sources and more than half of survey respondents think renewables are a good idea even if they raise energy bills.

Companies in the U.S. purchased a record 6.43 gigawatts of renewable power, enough to power 1.5 million homes.  The number of corporations entering into renewable energy deals doubled last year.

More than 300 U.S. cities, towns or counties have made commitments to climate action and, as of November, 99 cities have committed to 100% renewable energy, doubling the total from a year ago.

A number of gubernatorial candidates running on ambitious renewable energy platforms were elected in November including those in Illinois, Colorado, New Mexico, Maine and Nevada.

Utilities are responding to the growing demand for clean energy.  Consumers Energy in Michigan plans to cut carbon emissions by 80% and stop using coal.  Iowa-based MidAmerican Energy will become the first U.S. utility to source 100% of its electricity from renewable sources next year.  Xcel Energy, one of the biggest utilities in the country, has committed to be 80% carbon-free by 2030 and go completely carbon-free by 2050.

The fossil fuel industry with its supporters in high places is still kicking and screaming, but there is no doubt that the U.S. energy system is changing, and the quiet clean energy revolution will only pick up more steam in 2019.

Support For A Green New Deal

January 23, 2019 By EarthWise Leave a Comment

Shortly after the November election, activists held a sit-in at Nancy Pelosi’s office calling for a Green New Deal – a plan to transform the U.S. energy economy in order to mitigate the effects of climate change as well as address various issues of economic justice.   While a number of Congress people have pledged to back the creation of a select committee to develop such a plan, it remains a political football and it remains to be seen whether anything will come of the idea.

There appears to be much less reticence on the part of voters, at least according to a survey conducted by the Yale Program on Climate Change Communication at the end of November.  The survey gave a brief explanation of the Green New Deal and asked respondents “How much do you support or oppose this idea?”

The result was that 81% of registered voters either “strongly” or “somewhat” supported it.  Support was stronger among Democrats at 92%, but a majority of Republicans were also in favor.  Some 57% of self-identified conservative Republicans even thought it was a good idea.

The Green New Deal would accelerate the transition from fossil fuels to clean, renewable energy.  The goal would be to generate 100% of the nation’s electricity from renewable sources within the next 10 years; upgrade the nation’s energy grid, buildings, and transportation infrastructure; increase energy efficiency; invest in green technology research and development; and provide training for jobs in the new green economy.

Even though most Americans have strong support for the ideas of the Green New Deal, it is quite uncertain whether such an initiative could become a reality, given that very influential special interest groups – notably the fossil fuel industry – will be fighting it tooth and nail.

Peak Fossil Fuel Demand

There used to be a lot of talk about peak oil.  Peak oil was the theorized point in time when the maximum rate of extraction of petroleum was reached, after which there would be a terminal decline.  It was often presented as a looming catastrophe for civilization.

California vs. Fossil Fuels

California has led the way in deploying and committing to clean energy for a long time.  In August its legislature strengthened that commitment by passing a bill to stop using fossil fuels entirely by 2045.   It is the second state to do so, following Hawaii.  The bill still needs to be passed by the Senate and signed by the governor.  Both actions are expected to occur.

New Energy Goals For New York

Since 2015, New York has had in place an energy plan aimed at building a clean, resilient and cost-effective energy system for the state.  A key part of that plan is to reduce greenhouse gas emissions by 40% from 1990 levels by the year 2030.  Another major goal is to have 50% of the state’s electricity produced from renewable sources by the same year.

Hydrogen is touted to be the fuel of the future, particularly for cars.  But a more acccurate view of it is that hydrogen is an energy storage medium.  And the most promising form of energy to store using hydrogen is solar energy.

Many of our technologies produce waste heat.  Internal combustion engines are a prime example, but all our industrial processes, motors, electronics and other machinery turn some (and, in many cases, most) of the energy it takes to run them into heat that just goes into the environment.

Researchers in Belgium have engineered a device that uses sunlight to purify polluted air and, in the process, produces hydrogen gas that can be stored and used for power.  Two teams of researchers separately investigating processes for air purification and hydrogen production combined their efforts to create the new device.

Solar panels on the roofs of houses have become a familiar sight in recent years, but utility-scale solar – installations of 10 megawatts and greater – are really booming these days.   Throughout the United States, more than 10.5 gigawatts of utility-scale solar were added to the electric grid in 2016 – enough to power more than 2 million homes – and at least 8 gigawatts more are scheduled to come online this year.

Last year was a big year for progress in the U.S. power sector.  Renewable energy provided nearly 17% of the country’s electricity, up from 13.7% in 2015.  The first offshore wind farm in the U.S. opened off the coast of Rhode Island.  And most significantly, carbon emissions from the power sector continued to decline and reached the lowest levels in nearly 25 years.

Combating climate change is a bit like treating a disease whose early stage symptoms are not very severe.  People are not as motivated as they should be.   Businesses have to comply with new regulations and spend money on new technologies, which seems like a losing proposition.

Ocean energy is still one of the biggest untapped clean energy sources on the planet.  There are many studies that have shown that it could provide power for millions of homes in the U.S. alone.   But despite this, the technology is still in its infancy and it is unclear when and if it can become a major contributor to our energy needs.

Poor air quality is a serious problem.  Exposure to air pollution is linked to the premature deaths of an estimated 6.5 million people every year.  This makes air pollution the fourth largest threat to human health.  Only high blood pressure, dietary risks, and smoking are a bigger danger.
