Electric Cars And The Remote Road Test | Earth Wise

By Leave a Comment

One reason many people are hesitant about switching to an electric car is range anxiety, the fear that their car’s battery will die on them in the middle of a trip.  It is pretty much the same thing as running out of gas, but somehow it seems like more of a danger.

Perhaps this was true when charging stations were few and far between and electric cars couldn’t go very far on a charge, but these days, the average electric car can drive about 200 miles on a charge and there are charging stations all over the place.

A big difference between gas cars and electric cars is that many people can charge their cars at home and start every day with the equivalent of a full tank.  With an electric car, there is little reason to use up all nearly all the charge before filling up the tank again.

The truth is that most people don’t drive all that much on the average day anyway.  In the US, the average driver goes about 39 miles a day.  In Europe, is it considerably less.  Yes, there are some people who drive 200 miles a day, but they are few and far between.

Remote and regional Australia is a place where distances between essential services can be very large.  But a new study from the Australian National University found that even under those trying conditions, the vast majority of residents, about 93%, can go about their business even with the lower-range electric vehicles available on the market without having to recharge en route.

Electric cars may not be practical for some drivers, but for most, they are already a great choice.

Floating Offshore Wind | Earth Wise

By Leave a Comment

According to a new report by the Global Wind Energy Council, floating offshore wind technology is on track to grow from a miniscule market to a substantial contribution to the world’s energy supply over the next decade.  Furthermore, the United States represents one of the countries with the greatest potential.

Wind power is stronger and steadier in the ocean than on land, so the use of offshore wind is rapidly expanding.  However, because most installations are based on fixed structures attached to the sea bottom, they cannot be installed in very deep or complex seabed locations.

Floating offshore wind is based on structures that are anchored to the seabed only by means of flexible anchors, chains, or steel cables.  Apart from making it feasible to place wind turbines in deeper and more distant locations, floating turbines and platforms can also be built and assembled on land and then towed to the offshore installation site.

The floating offshore wind industry is currently in a pre-commercial phase but has great potential.  Many offshore locations with great potential in terms of their wind resources are unsuitable for conventional installations either because of the depth of the seabed or its complex structure.  This is particularly true of the waters off the coasts of California, Oregon, and the Gulf Coast, which otherwise offer excellent wind resources.

There are many issues to deal with in expanding the use of floating offshore wind, including transporting the power to shore and the ability of the local power grids to handle the incoming power.  On the other hand, distantly placed floating offshore wind reduces environmental concerns and eliminates issues associated with the visual impact of wind farms for coastal residents.

Clean Energy In Rochester | Earth Wise

By Leave a Comment

New York’s largest community choice clean energy program has been activated in the City of Rochester.   The program, offered by Rochester Community Power, offers 57,000 residences and small businesses access to clean energy from hydropower and wind sources.  It requires customers to opt out rather than enroll in order to provide clean energy to the greatest number of people.

Rochester Community Power is the city’s local community choice aggregation (CCA) program that leverages the collective buying power of participating residents to purchase renewable electricity and negotiate better terms for energy supply contracts.

The program will supply customers with more than 300 million kWh of renewable energy each year, which will avoid the emission of about 250,000 tons of carbon dioxide.  Rochester plans to add a community solar program next year which will provide additional clean energy opportunities, including offering guaranteed savings to thousands of participants in its Home Energy Assistance Program.

The project will be managed by Joule Assets, which is a provider of energy reduction market analysis, tools, and financing. Joule Assets, as program administrator for the Rochester program, managed the competitive bidding process that secured a fixed rate for electricity for the next two years, shielding participating residences and businesses from volatile market prices.

Community choice aggregation programs are local, not-for-profit public agencies that are an alternative to investor-owned utilities.  They give municipalities the ability to make decisions about the procurement, sourcing, and rates for energy for its residents.

California’s Silent Health Hazard | Earth Wise

By Leave a Comment

For people in the Los Angeles area, it is a familiar sight to see oil wells pumping away on hillsides, in residential neighborhoods, and other places.  In fancier parts of town, oil wells are hidden behind facades located next door to dry cleaners and lamp stores.

Every year, more than 140 million barrels of oil are extracted from the state of California, coming from a vast subterranean formation that spans nearly the entire state along the coast and spreading inland as well.  About 30% of the state’s oil comes from the Los Angeles area.

The oilfields are mostly old, and their wells played out.  As a result, high-tech drilling and a slew of toxic chemicals are needed to extract the last dregs of crude oil.

Unlike more rural oil-producing states, where oilfields might be uninhabited except for the people who work on them, drilling in California happens to a large degree in residential settings.  Over the years, it has become increasingly clear that certain chemical byproducts of oil extraction, among them benzene and hydrogen sulfate, can cause a variety of health problems.  For example, recent research has found connections between exposure to oil and gas well sites and spontaneous pre-term births, low-birthweight babies, and other adverse birth outcomes.

Statewide, little is being done to protect residents and schoolchildren from any of the suspected consequences of living near an oil or gas well.  Regulations are weak and spottily enforced because the oil industry still wields a lot of political power in the state.  Environmental groups and justice advocates are actively seeking to create new protections for California citizens, but it remains an uphill battle.

Compost And Landfills | Earth Wise

By Leave a Comment

Composting is popular as a way to keep solid waste out of landfills and many people turn much of their kitchen waste into rich soil amendments.   Cities and towns across the country have composting programs that collect waste from residents to produce large quantities of compost rather than adding the waste to landfills.  A new study from North Carolina State University looked into the environmental benefits of actually using compost at landfills.

Most municipal composting programs require that the compost they produce gets used “beneficially”.  The new research shows that using compost as an alternative daily cover at landfills is competitive and often superior to the use of compost as a soil amendment in terms of its environmental benefits.

Landfills apply a layer of daily cover to reduce odors, reduce windblown debris, and keep vermin out of landfill waste.  Federal regulations require six inches of soil as a daily cover.

Compost from food waste in particular is not always suitable for soil amendment in gardens and agricultural fields because it often contains broken glass and other contaminants.

The North Carolina State study looked at the environmental impact of using compost as daily cover in landfills compared with its use as a soil amendment.  They looked at global warming potential, acidification potential, eutrophication (which is the amount of nutrients released to ground and surface water), cumulative energy demand, and the depletion of resources.

The study concluded that using compost as landfill daily cover is environmentally superior with regard to eutrophication, acidification, and global warming potential.  On the other hand, soil amendment was better in terms of resource depletion and cumulative energy demand.

The Changing Climate Is Changing Insurance

By Leave a Comment

As the climate changes, wildfires get bigger and more destructive and hurricanes and powerful storms are more frequent and damaging.  In places where these things are occurring, it is getting harder and more expensive for many homeowners to get insurance.  The affordability of home insurance in the face of climate change has become a huge issue in many states.

In California, the number of homeowners who got non-renewal notices from their insurance companies rose by 6% between 2017 and 2018.  In areas directly affected by wildfires between 2015 and 2017, that number jumped by 10%. Similar things have happened in Florida, Louisiana, Mississippi, and Texas, where hurricanes and flooding have caused extensive damage.  Because of this, many homeowners have been forced to turn to bare-bone plans such as the California Fair Access to Insurance Plan, which can cost two or three times as much as normal insurance policies.

According to a 2019 survey of insurance companies, more than half of insurance regulators said that climate change was likely to have a high impact or an extremely high impact on the availability of insurance coverage and the assumptions used for underwriting.  In the past, governments have been able to mandate coverage in certain areas or even provide coverage themselves in some cases.  As the occurrence of climate-related damage becomes increasingly frequent, homeowners have to face up to a grim reality.

The challenges of dealing with wildfires, floods, powerful storms, and the like are significant enough for people who live in high-risk areas.  Increasingly, home insurance in these places is becoming much more expensive, harder to find, and is worth less.

Europe Is Warming Faster Than Predicted

By Leave a Comment

A new study has found that Europe is warming faster than even climate models projected.  The number of summer days with extreme heat in Europe has tripled since the 1950s, while the number of days with extreme cold has decreased by factors of two or three depending on the region.

According to climate scientists at the Swiss Federal Institute of Technology in Zurich, the climate trends are much larger than what would come from natural variability and are a clear signal of climate change.  Extremely hot days in Europe have become hotter by an average of more than 4 degrees Fahrenheit while extremely cold days have warmed by more than 5 degrees.  The research examined data from weather stations across Europe from 1950 to 2018.  Over 90% of the stations recorded increasing temperatures over time, a percentage much too high to be purely from natural climate variability.  The results also showed that the region was warming even faster than climate models projected.

The research results come after an extremely hot summer in Europe.  Southern France hit 114.8 degrees, a new record, in June.  Germany, the Netherlands, and Belgium all recorded all-time national temperature highs.  The National Oceanic and Atmospheric Administration recently announced that July was the hottest month ever recorded.

European summers and winters will only grow hotter in the coming years as climate change accelerates.  The rapidly increasing temperatures will impact cities and people that are unprepared for them and pose real risks for residents in the coming decades.  Extreme heat is dangerous because it stresses the human body, potentially leading to heat exhaustion or heat stroke.

Capital Region Community Solar

By Leave a Comment

New York’s Capital Region is getting a major new community solar farm.  A community solar farm is a solar power installation whose output is shared by multiple community subscribers who receive credit on their electricity bills for their share of the power produced.  The primary purpose of community solar is to allow members of a community to have the benefits of solar power even if they cannot or prefer not to install solar panels on their own property.

US Light Energy has broken ground on the Sugar Hill Solar Farm, to be located on 40 acres of land on the Sugar-Hill/Sugar-View Farm in Clifton Park.  The 7-megawatt, ground-mounted solar project will include nearly 20,000 solar modules.  When fully operational later this year, the facility is expected to produce more than 8.6 million kilowatt-hours of energy a year.

The farm will be part of New York state’s Community Solar Program, and the electricity it generates can be supplied to customers anywhere in National Grid’s existing distribution system.  Residential and commercial properties in Clifton Park will have 30 days to subscribe before the solar energy generated by the farm is opened to the general public.  Subscribers of community solar farms typically save 10% on their electricity bills.

There are already community solar programs in operation in several Capital Region communities, but this is the first one in the Clifton Park Area.  Apart from providing savings on utility bills, community solar allows consumers to support clean, locally generated power with little or no upfront costs.  Not everyone is in a position to put solar panels on their roof, but community solar is increasingly an option for New York residents.

Listening To Volcanoes

By Leave a Comment

Volcanoes are complicated, and we don’t have universally applicable ways to predict when they might erupt.  Measurements of seismicity, gas emissions and ground deformation are all useful in trying to figure out what volcanoes are up to.  However, it is unlikely that will ever have definitive prediction techniques.

How Safe Is Drinking Water?

By Leave a Comment

Water is life.  It’s a fundamental need for every human being on the planet.  Each person requires more than five gallons of clean and safe water a day for drinking, cooking, and keeping clean.  Dirty water, on the other hand, can be deadly.  An estimated 1.8 million people die every year as a result of diarrheal diseases like cholera.  And tens of millions of people are seriously sickened by water-related maladies.

Alaska’s Threatened Communities

By

Because of its Arctic location, Alaska is warming about twice as fast as the rest of the United States.   The past year has been the warmest on record.  The forces of erosion and increasingly powerful storms have resulted in the imminent risk of destruction for at least 31 Alaskan towns and cities.   Many are predicted to become uninhabitable over the next few decades.  Residents of these places are likely to join the growing flow of climate refugees around the globe.

Social And Ecological Underpinnings Of Infectious Disease

When it comes to addressing infectious disease, we have a short attention span. Forces are mobilized when we’ve crossed a tipping point, and demobilized when the immediate threat has passed. In the case of Zika, the World Health Organization declared a public health emergency based on a strong association between Zika infection and microcephaly in newborns and a spike in Guillain-Barré syndrome.
