New York And Renewables | Earth Wise

January 7, 2021 By EarthWise Leave a Comment

In 2019, New York generated more electricity from renewable sources than all but three other states. The 39.4 million MWh of renewable electricity generated in New York was the largest of any state east of the Mississippi.

New York has been a leader in renewable power long before it became a topic of great interest because of its hydroelectric power. In 2019, 78% of the state’s renewable electricity came from hydropower. The Robert Moses Niagara hydroelectric plant is the second-largest capacity conventional hydroelectric power plant in the country.

The three states that generated more renewable electricity than New York are California, Texas, and Washington. Washington gets 69% of all its electricity generation from its multiple hydroelectric plants which together produce a quarter of all hydroelectric power in the nation. Texas leads the nation in wind-powered generation and gets over 17% of its in-state generation from wind. California gets 14% of its power from solar generation, 7% from wind, and over 16% from its own hydroelectric resources.

Wind is the second-largest source of renewable power in New York, accounting for 11% of renewable generation in the state and 3% of total electricity generation. Solar power is expanding in New York, but the great majority of it is still in the form of small-scale installations on residential and commercial rooftops.

New York’s renewable generation grew from 19% in 2005 to 30% at present. New York’s Clean Energy Standard adopted in 2015 requires the state to generate 100% carbon-free electricity by 2040.

The Changing Climate Is Changing Insurance

October 21, 2020 By EarthWise 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.

The Dead Zone In The Gulf Of Mexico | Earth Wise

July 6, 2020 By EarthWise Leave a Comment

The Gulf of Mexico has an area of low to no oxygen in the water that can kill fish and other marine life. It is an annual event that is primarily caused by excess nutrient pollution from human activities in urban and agricultural areas throughout the Mississippi River watershed. When these excess nutrients reach the Gulf, they stimulate the overgrowth of algae, which eventually die and decompose, depleting the oxygen in the water as the algae sink to the bottom.

These low oxygen levels near the bottom of the Gulf cannot support most marine life. Some species – among them many fish, shrimp, and crabs – swim out of the area, but animals that can’t swim or move away are stressed or killed by the low oxygen. The dead zone in the Gulf occurs every summer.

A recent forecast for this summer’s dead zone predicts that the area of low or no oxygen will be approximate 6,700 square miles, which is roughly the size of Connecticut and Delaware combined. This is about 1,100 square miles smaller than last year’s dead zone and much less than the record of 8,776 square miles set in 2017. But it is still larger than the long-term average size of 5,387 square miles.

Making comparisons to the long-term average ignores the fact that the long-term average itself is unacceptable. The dead zone not only hurts marine life, but it also harms commercial and recreational fisheries and the communities they support. The actions that have been taken so far to reduce pollution in the Mississippi watershed are clearly not sufficient to drastically reduce the dead zone in the Gulf.

Global Warming And The Nitrogen Problem

September 13, 2017 By EarthWise

Excess nitrogen in the environment is a big problem. The most visible aspect of the problem is the spread of toxic algae blooms in oceans, lakes and other bodies of water. But there are other effects as well such as unwanted alterations to ecosystems.

Restoring Sediment To Save Wetlands

August 25, 2017 By EarthWise

The world’s rivers carry billions of cubic yards of sediment – sand, silt and other material – and transport it to wetlands and coastal areas. Until fairly recently, this was viewed as a negative thing. But that has changed.

Clean Coal For Real

February 20, 2017 By EarthWise

We have heard the term “clean coal” for years, mostly from politicians and in coal company advertising. The concept sounds good: burn coal but don’t produce carbon dioxide emissions. While there have been various small-scale tests of technologies to accomplish this, it has not actually been a viable option for the power industry.

Global Climate Or Local Weather?

January 25, 2017 By EarthWise

We don’t experience climate; we experience weather. And a new study has found that what Americans believe about the changing climate often depends more on their personal experience than what is going on around the world.

The BP Oil Spill

May 16, 2016 By WAMC WEB

In 2010, an explosion on the BP-owned Deepwater Horizon drilling rig released more than 200 million gallons of oil into the Gulf of Mexico. Some of the oil was recovered, burned, or dispersed at sea, while some washed up onto the shorelines of Texas, Louisiana, Mississippi, Alabama, and Florida.
