Lake George Health Report

December 26, 2019 By EarthWise Leave a Comment

The Offshore Chemistry Program, run by the Darrin Fresh Water Institute at RPI, has been monitoring the deep waters of Lake George in New York for 40 years. Lake George, nicknamed the Queen of American Lakes, is famed for the transparency of its water and a new report on the health of the lake reveals that it is doing rather well.

According to the report, although concentrations of chemicals and pollutants like salt and nutrients have increased in the deep waters of Lake George, they are still too low to harm the ecosystem at those depths.

The Offshore Chemistry Program studies the lake as part of a collaboration between RPI, IBM Research, and the FUND for Lake George that is called the Jefferson Project. This long-term commitment provides a wealth of information over time matched by few lake studies in the world.

The recent results show that levels of salt, the nutrient orthophosphate, and chlorophyll have increased substantially over time, but none are yet at a level that will cause harm.

Orthophosphate occurs naturally, but most likely the higher levels are due to improperly functioning septic systems, failing wastewater treatment systems, and stormwater runoff. The orthophosphate most likely triggered the increase in chlorophyll, which probably is associated with increased density of chlorophyll in individual algal cells, rather than an increase in total algal mass in the lake.

Overall, the results demonstrate the continuing resilience of Lake George to a growing array of stressors. In nearly 40 years of human activities, the lake has changed in a number of ways, but the changes have so far been relatively small. With such careful monitoring, we can hope to keep them that way.

Should New York Build A Storm Surge Barrier?

December 6, 2019 By EarthWise Leave a Comment

In 2012, Superstorm Sandy’s storm surge combined with a high tide and buried lower Manhattan under 13 feet of water. Across all five boroughs, subways, highways, and parking garages flooded and homes and businesses were destroyed. Sandy caused nearly $20 billion in damages in New York City alone and more than 50 people died.

Ever since that disaster took place, there have been discussions about building storm surge barriers to protect the city from future storms. Columbia University’s Sabin Center recently hosted an event to discuss the feasibility of building such barriers.

A study by the U.S. Army Corps of Engineers called the NY and NJ Harbor and Tributaries Focus Area Feasibility Study (HATS, for short) evaluates five options for coastal protection, which range in scope and price.

The most extensive option would involve constructing six miles of storm surge gates along with 26 miles of floodwalls, levees, and buried seawalls. This option would cost $62 billion but could theoretically save $131 billion in damages and protect 95% of the study area.

The study also considers the side effects of building storm surge barriers. These include environmental impacts such as effects on fish and wildlife, water quality, noise and vibrations, and changes in water flow. While these effects can be quite serious and there is opposition from many quarters related to environmental impacts, others point out that there is really no other credible defense against storm surge. The debate over whether or not to build storm surge barriers could easily last for many more years.

In the bigger picture, storm surge barriers do nothing to protect against rain-driven flooding, sea level rise, and tidal floods which continue to increase.

Cleaner Air Saves Lives

September 25, 2019 By EarthWise Leave a Comment

A new study by Columbia University has concluded that lower air pollution levels saved an estimated 5,660 lives in New York State in 2012, compared to 2002 mortality levels.

The study looked at New York State levels of the specific type of pollution known as fine particulate matter, referred to as PM2.5. These microscopic particulates are a mixture of solid particles and liquid droplets that either come from burning fuel or are formed in the atmosphere as a result of complex reactions of chemicals such as sulfur dioxide and nitrogen oxides from power plants, industries, and automobiles.

Long-term exposure to PM2.5 can lead to respiratory and cardiovascular problems.

The study looked at extensive amounts of data to analyze trends in PM2.5 levels across New York State. The data showed that PM2.5 levels dropped by 28 to 37% between 2002 and 2012. This was a result of continued progress in cleaner vehicles, the reduction of high sulfur-dioxide emitting coal-burning power plants, and other air pollution reduction programs. They calculated that this amount of reduction in PM2.5 reduced the air pollution mortality burden for New York State residents by 67% – from 8,410 premature deaths in 2002 to 2,750 deaths in 2012.

The study provides evidence that emission controls on air pollutants – which were initiated by the Clean Air Act of 1970 and later expanded in 1990 – have improved public health across New York State. According to the researchers, the study is a key step to documenting the health benefits from cleaner air.

New York Offshore Wind

September 18, 2019 By EarthWise Leave a Comment

New York has passed ambitious legislation to reduce the carbon emissions that cause climate change, but the state needs to start taking action to make those reductions possible. One such action it has taken is an agreement that will enable the construction of two large offshore wind projects.

The projects are to be built off the coast of Long Island. One will be 14 miles south of Jones Beach and the other 30 miles north of Montauk. The wind farms will be built by a division of Equinor, a major Danish energy company, and a joint venture between Orsted, another Danish company, and Eversource Energy, an American firm.

The two New York wind farms are expected to be operational within the next five years and have the capacity to produce 1,700 megawatts of electricity. That is about 20% of Governor Andrew Cuomo’s overall goal for offshore wind.

Wind farms are a major energy source in the United States, now providing about 7% of the country’s electricity. That compares with only 2% in 2010. But nearly all American wind turbines are on land. There is only one small offshore wind farm in the US off the coast of Rhode Island. Things are very different in Europe. For example, Britain expects to get 10% of its electricity from offshore wind next year, which is up from less than 1% in 2010.

Developers of offshore wind farms have struggled to gain a foothold in the US. Some projects have foundered because of cost issues, but others have faced opposition from politicians and coastal-property owners. But assuming the New York wind projects clear permitting and environmental hurdles, offshore wind may finally be on the move in the US.

Booming Electric Car Sales

September 12, 2019 By EarthWise Leave a Comment

Electric cars are becoming more and more commonplace over time. There is no place in the world where this is more evident than in Norway. This year, about half the new cars sold in Norway have been electric. This compares to only 25% just last year. In March alone, nearly 60% of vehicle purchases in Norway were plug-in cars, outselling gas and diesel cars for the first time ever.

Norway has encouraged the switch to electric transportation by making battery-powered cars tax exempt as well as offering various other incentives. This is all part of the country’s plan to end the sale of fossil fuel cars entirely by 2025.

Although Norway leads the world in electric car sales on a per capita basis, there are many other places seeing rapid growth. In Maryland, for example, so many electric cars were sold in the past year that the state’s tax credit program, which has a $3 million annual budget, ran out of money seven months before the end of the fiscal year. Between 2017 and 2018, the number of EVs registered in Maryland doubled to over 18,000.

New York has also seen robust growth in electric vehicles. There are now more than 40,000 plug-in cars registered in New York State. About a third of those are Tesla models, with the increasingly popular Tesla Model 3 rapidly becoming the dominant plug-in car in the state. In fact, this year the Tesla Model 3 has accounted for about 60% of all plug-in car sales in the United States.

Not only are electric car sales going up, so are the options for car buyers. Within the next year or two, there will be numerous new electric car choices available from multiple manufacturers appealing to the tastes of a growing range of car buyers.

Off-The-Charts Heat

August 9, 2019 By EarthWise Leave a Comment

There have been some blistering heatwaves this summer – in Europe, in the Middle East, and here in the United States. A new report by the Union of Concerned Scientists projects that within the next 20 years, millions of people in the United States could be exposed to dangerous “off-the-charts” heat index conditions of 127 degrees Fahrenheit or more. Within 60 years, over one-third of the population could be exposed to such conditions.

Extreme heat kills hundreds of people every year across the U.S. Our bodies’ natural cooling process is affected by humidity and the combined heat index measures the impact of high temperature and high humidity. When the combined heat index reaches 90 degrees, it is considered to be a “dangerous day”, when many groups of people are at serious risk.

Because of the warming climate, the number of dangerous days has been increasing in many parts of the country. Unless there is success in limiting the effects of climate change, by 2050, even relatively temperate cities like Detroit, Minneapolis, New York, and Chicago will have 50 or more dangerous days a year. Places like Dallas, Houston, Phoenix and Miami will experience dangerous days for half of the year.

The National Weather Service’s heat index goes up to 127 degrees Fahrenheit. But in as soon as 20 years, the Southeast, Southern Great Plains, and Midwest will begin to experience days that are so hot that they are “off the charts.”

These extreme conditions could still be avoided with steep, rapid carbon emission reductions. But however successful we are going forward, the US will still be significantly warmer than today with 85 urban areas exposed to 30 or more days with a heat index above 105 degrees, compared with just three urban areas historically.

Packing With Banana Leaves

July 25, 2019 By EarthWise Leave a Comment

More and more places are instituting bans on single-use plastic bags. Places like California and Hawaii already have bans in place and New Jersey is considering such a ban. New York’s law will go into effect next March. Supermarkets will no longer provide plastic bags at the checkout line. But the laws have some exceptions, including the plastic bags used to hold produce and to pack up meats.

Banning or reducing single-use plastic bags is a growing trend in Asia as well including places like South Korea, Vietnam and Thailand.

One supermarket in Thailand came up with a novel approach to eco-friendly packaging: wrapping produce in banana leaves. The idea quickly became a viral hit on social media and drew the attention of supermarkets in Vietnam. Several big supermarket chains in that country also began experimenting with banana leaves as a packaging alternative.

Representatives of Vietnam’s Lotte Mart chain said that the banana leaf packaging was still in the testing phase, but they plan to replace plastic with leaves nationwide very soon. Aside from wrapping vegetables and fruits, the grocery chain intends to also use the leaves for fresh meat products.

Customers seem to be quite positive about the new packaging noting that it is actually quite attractive visually. The banana leaf packaging also makes people more aware of the need for protecting the environment.

While Vietnam is a relatively small country, it turns out that it ranks number four in the world for the largest amount of plastic waste dumped into the ocean. The country disposes of about 2,500 tons of plastic waste per day. So, efforts like the banana leaf packaging are not just symbolically important, they are genuinely a major environmental imperative.

The New York Climate Plan

July 24, 2019 By EarthWise Leave a Comment

New York lawmakers have passed a sweeping climate plan that requires the state to eliminate almost all of its greenhouse gas emissions by 2050. The plan calls for the phase-out of gasoline cars and oil- and gas-burning furnaces and requires all of the state’s electricity to come from carbon-free sources.

The Climate Leadership and Community Protection Act requires the state to slash its carbon emissions to 85% below 1990 levels by 2050 and to offset the remaining 15% by other means such as removing carbon dioxide from the atmosphere. The bill requires New York to get 70% of its electricity from renewable sources by 2030.

The challenges of reaching the program’s goals are daunting. New York has so far only reduced its emissions by 8% since 1990. The state currently does get 60% of its electricity from carbon-free sources – mostly hydroelectric dams and nuclear power plants – but it will require offshore windfarms, ramped-up solar installations, and battery storage systems to push the numbers dramatically higher.

Transportation, which is responsible for a third of New York’s emissions, will be particularly tough to tackle. The Trump administration is rolling back federal vehicle efficiency rules and is trying to prevent states from setting stricter standards. Currently, electric car ownership is primarily attractive for single-family homeowners who can plug in their cars at home. Far more pervasive charging stations – for example, all over the streets of New York City – would be needed to make electric cars practical for everyone.

The plan aims for industries to bear most of the financial burden, but supporters say that the costs of not acting on climate will be vastly greater for businesses. The plan’s deadlines for major emissions reductions are a decade away but there will be much to do quite soon.

Capital Region Community Solar

July 19, 2019 By EarthWise 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.

Complications For New York Solar Farms

July 12, 2019 By EarthWise Leave a Comment

A study by engineers at Cornell University looked at the implications of adding utility-scale solar farms throughout New York State. Adding such farms could reduce demand for electricity from conventional sources by nearly 10% in some places. But the engineers caution that winters in upstate New York could create some novel problems for the state’s power system.

Electrical energy demand tends to be low around midday when many people are not home. Electrical production from solar farms is high at that time when the sun is at its highest position in the sky. This can lead to what power system operators call “ramping”, which is the term for rapid increases or decreases in demand.

This sort of ramping was first discussed in California years ago. When people wake up and prepare for the day, there is a morning peak in electrical load, which occurs before solar production ramps up. When people get home from work in the evening, energy demands create a second peak. A graph of this lack of synchronicity of load and supply looks a little like the shape of a duck and is popularly known as the duck curve.

The Cornell engineers figured out that maximum ramping in New York – where electrical demand and electricity supply from solar farms are out of synch- will take place in the winter. In fact, when there are several days of sunshine in a row during winter, the largest ramping in the New York power system will take place.

The general issue of having solar energy available when it is most needed is one that is the driver for energy storage technology. If the energy can be provided when demand calls for it, there would be no more ramping.

Two Million Solar Installations

July 1, 2019 By EarthWise Leave a Comment

Three years ago, we reported that the United States had installed its one millionth solar energy system, a feat that took 40 years to accomplish. Recently, the Solar Energy Industries Association announced that there are now more than 2 million U.S. installations.

Analysts forecast that there will be 3 million installation in 2021 and 4 million in 2023.

California continues to lead the nation in installing solar power. More than 50% of the first million installations were in that state and California accounted for 43% of the second million. Its share is nevertheless slowly dropping with the growth of the residential solar sector that is rapidly diversifying across state markets. Some places have seen extremely rapid growth. In South Carolina, there were barely more than 1,000 cumulative installations in 2016; today, the state is home to more than 18,000 solar systems and expects to add 22,000 more over the next five years.

The five leading states in terms of number of solar installations are California, Arizona, New York, New Jersey, and Massachusetts. Other states recently seeing rapid growth in solar installations are Texas, Utah, Florida, Rhode Island and Maryland. Looking ahead, Illinois is forecast to grow from only 4,000 installations today to nearly 100,000 by 2024. The top ten state markets apart from California expect to add nearly 750,000 installation over the next five years.

The United States is at least the third nation that is home to more than 2 million solar installations. (Australia hit the milestone late least year and Japan actually topped 2 million in September 2014).

According to forecasts from analyst first Wood Mackenzie, by the year 2024, there will be on average one new solar installation every minute.

Getting Rid Of Plastic Here And Abroad

May 23, 2019 By EarthWise Leave a Comment

Efforts in the fight against plastic pollution are really stepping up these days.

New York State lawmakers have agreed to impose a statewide ban on most types of single-use plastic bags from retail sales. The ban would be the second statewide ban after California, which banned the bags in 2016. Hawaii effectively also has such a ban since all of the state’s counties have their own bans.

The New York ban would begin next March and would forbid stores from providing customers with single-use plastic bags. There are a number of exceptions, including food takeout bags in restaurants, bags used to wrap deli or meat counter products, and newspaper bags. New York counties could opt into a plan to charge a 5-cent fee on paper bags, with proceeds going to the state’s Environmental Protection Fund. Some environmentalists point out, however, that paper bags have their own issues. While they do decompose in landfills, they have a substantial carbon footprint since they are made from wood and being heavier, they are more costly to ship. Business groups are concerned about the forthcoming ban based on increased costs.

Meanwhile, European Union member states have reached a provisional agreement to introduce restrictions on single-use plastic products. In 2021. European citizens will say goodbye to plastic cutlery, plastic plates and plastic straws among other products.

According to the European Commission, plastics make up 85% of beach litter in the Mediterranean. Large plastic pieces injure, suffocate, and often kill marine animals but microplastics have reached record levels of concentration – over a million fragments per square kilometer – in the Mediterranean.

Both here and abroad, the war on plastics is heating up.
