Balloon release laws

May 27, 2024 By EarthWise Leave a Comment

The Florida state legislature has recently passed a law that bans the intentional release of helium balloons outdoors. It is a rare example of a bipartisan piece of legislation. Florida is joining six other states that have already enacted balloon restricting laws.

Balloons released into the sky don’t just disappear into the ether. They often end up in oceans and waterways and the thin material that remains is 32 times more likely to kill seabirds than other types of plastic debris. Aquatic animals often mistake balloons for jellyfish and fill up on them. Balloons tied up with ribbons entangle turtles and manatees. Even grazing cows have died from ingesting balloons. Balloons contribute to microplastic pollution, which is a growing problem for all living things, including humans.

Other states with balloon release laws are Connecticut, Tennessee, New York, Texas, California, and Virginia. Details of the laws vary. They carve out exceptions for specific applications. They exempt small children. Some limit the quantity of balloon release. Others require balloons to be weighted down to prevent them from rising too high. California’s legislation is aimed at the metallized mylar balloons that have shorted out high-tension electrical wires and triggered wildfires.

The Florida law equates intentionally releasing a lighter-than-air balloon with littering. It’s a non-criminal offense that carries a fine of $150.

People enjoy releasing helium balloons, particularly en masse. The spectacle has become part of weddings, gender reveal parties, and even funerals. But the practice has serious environmental repercussions, and its restriction is being pursued by more and more states and municipalities.

Cleaning the grid can create messes

January 9, 2024 By EarthWise Leave a Comment

The electric grid is increasingly embracing renewable energy sources like solar and wind power as well as the energy storage systems that support them. These generation sources differ from traditional sources in that they produce direct current electricity rather than alternating current electricity. Our power grid runs on alternating current. Traditional generators produce alternating current that synchronizes with the grid. Wind and solar power connect to the grid using electronic power converters called inverters that produce the required alternating current.

All of this technical detail is something we don’t pay much attention to, except that the current state of inverter technology can lead to some problems that don’t exist with a fully synchronous power system.

The electric grid frequently experiences disruptive events like trees falling on powerlines, squirrels shorting out substation equipment, and so on. These things normally don’t cause widespread trouble, although there have been notable exceptions such as the massive Northeast blackout of 2003 triggered by an overloaded transmission line drooping onto foliage.

The issue with inverters is that they can shut down in the presence of certain disturbances to the grid. This has happened on a number of occasions and has exposed vulnerabilities that need to be addressed by the industry. Inverter-based resources currently constitute only a relatively small fraction of the grid, but that fraction is growing steadily and can have an increasingly widespread impact. The grid was built predominantly for synchronous generation, and it must be adapted and improved to assure the reliability that is required and expected. It is an issue that can’t be ignored.

New York’s Polystyrene Foam Ban | Earth Wise

January 19, 2022 By EarthWise Leave a Comment

As of January 1, the state of New York now prohibits any person engaged in the business of selling or distributing prepared food or beverages from selling, offering for sale, or distributing disposable food service containers that contain expanded polystyrene foam in the state. In addition, no manufacturer will be allowed to sell, offer for sale, or distribute polystyrene loose fill packaging in the state.

In other words, there will be no more Styrofoam bowls, cartons, clamshell containers, lids, plates, trays, or packing peanuts.

There are still some exceptions. Raw meat, seafood, poultry, or fish sold for the purpose of cooking or preparing off-premises can still be packaged in polystyrene foam. Prepackaged food filled or sealed prior to receipt by a food service provider can also still be packaged in polystyrene foam.

The New York State Department of Environmental Conservation is initially focusing its efforts on outreach and education to achieve compliance rather than on enforcement. The DEC has provided detailed regulations to assist stakeholders with complying with the law.

Expanded polystyrene foam is a major contributor to environmental litter. The material breaks apart easily and does not readily biodegrade, causing it to be persistent in the environment and contribute to microplastic pollution. The foam causes negative impacts to wildlife, waterways, and natural resources.

An estimated 65% of New Yorkers were already living in communities that banned polystyrene foam, notably including New York City and Long Island which imposed a ban in 2019.

New York becomes the fourth state to impose such a ban after Maine, Maryland, and Vermont. Colorado and Virginia will follow suit in the next two years.

Electric Cars And The Environment | Earth Wise

April 20, 2020 By EarthWise Leave a Comment

There are articles in the media all the time questioning whether electric cars are really better for the environment than those powered by fossil fuels. The usual argument is that once emissions from vehicle production and electricity generation are taken into account, electric cars are no greener than gas cars, or even worse for the environment. Of course, these arguments tend to be made by oil companies and their supporters.

A new study by three European universities looked at this very issue in detail. They carried out a life-cycle assessment in which they not only calculated greenhouse gas emissions generated when using cars, but also in the production chain and waste processing.

Their conclusions are that under current conditions, driving an electric car is better for the climate than conventional gasoline cars in 95% of the world. The only exceptions are places like Poland, where almost all electricity comes from coal-fired plants.

Average lifetime emissions associated with electric cars are up to 70% lower than gas cars in countries like Sweden and France and about 30% lower in England.

It is important to note than in a few years, even inefficient electric cars will be less emission-intensive than gas cars because electricity generation is becoming less carbon-intensive all the time. The study projects that by 2050, half of the world’s cars will be electric resulting in carbon dioxide emission reductions of 1.5 billion tons.

The study states that the idea that electric cars could increase emissions is a myth. The detailed study has run the numbers for all around the world and even in the worst-case scenario, there would be a reduction in emissions in almost all cases.

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.
