Waste Companies Turning Food Waste to Energy

November 26, 2018
food waste to energy

About one-third of the food the world produces each year for consumption by humans gets wasted or lost. In fact, they throw away up to $2,200 in food per year. This creates a financial burden for families as well as waste companies and municipalities that must determine what to do with all this waste. New York City, for example, spends about $400 million each year shipping the waste it collects to landfills and incinerators across the country.

This wasted food also has a significant environmental impact. It represents a lot of wasted resources — not just the food itself, but also the land, water and energy it took to produce it. Food decomposing in landfills also releases a gas composed of approximately 50 percent methane and 50 percent carbon dioxide, both of which contribute to the greenhouse effect. Landfills are responsible for about 14 percent of human-related methane emissions in the U.S.

There are various efforts underway to prevent this food waste and its negative impacts. In 2015, the United States Department of Agriculture (USDA) and the Environmental Protection Agency (EPA) set the nation’s food waste reduction goals, which aimed to cut waste by 50 percent by 2030.

Are Wind and Solar Viable Options for 100% Renewable Energy?

November 9, 2018

As public concern over climate change increases, more people see the need for sustainable energy production. Traditional power generation relies on burning fossil fuels like coal and natural gas, a process which releases the warming greenhouse gas carbon dioxide into the atmosphere. Renewable energy sources like wind and solar aim to produce essential energy without the carbon emissions.

The popular demand for 100 percent renewable energy, reflected in public opinion and policy in states like California, has lead to increased investment in wind and solar power in recent years. Despite growing interest in renewable energy, it remains unclear whether renewable energy alone can get us to a zero-carbon future.

Wind and solar power represent great potential for clean, renewable electricity. However, they may not fill all the world’s energy needs by themselves. Let’s examine wind and solar as a path to 100 percent renewable energy and consider possible alternative solutions.

Free Solar for Low-Income Families Offers Promising Future for Renewable Energy

October 4, 2018

Reliance on fossil fuel paints a grim picture of the future. Heavy pollution and poor air quality, tainted groundwater and ravaged ecosystems comprise a landscape where nothing grows — the Earth salted without hope of restoration. Given the current political climate, this is a pressing threat.

The optimistic men and women at GRID Alternatives Mid-Atlantic picture the future differently. They view the future as one of long-term sustainable energy, using affordable alternatives to conventional methods to preserve the environment while enjoying the same level of comfort and convenience.

In their picture of the future, the air is clean, the groundwater is clear and wildlife receives the respect it deserves. The grass grows a little greener, and harmony exists between the natural and artificial. So how is GRID working toward making this dream a reality?

How Renewables Can Prevail Despite Trump’s Renewable Energy Policy

September 20, 2018
Trump's renewable energy policy

America’s Trump-Republican government has rendered its judgment on climate change with vast silence and outlined its renewable energy policy by doubling-down on coal. We thought Trump’s renewable energy policy would reach “peak contrarian” when we pulled out of the Paris Climate Accord. But the truth is, we’ll scarcely have a single environmental regulation on the books by the time this administration is shown the door.

The good news is, there’s lots of good news. We don’t have to get partisan about the damage done when the wrong people get elected. Let’s focus instead on the undeniable momentum behind the pivot to renewable energy, despite Trump’s renewable energy policy.

Understanding that the U.S. is just one piece of the global puzzle, and that what’s happening here is raising consciousness elsewhere in the world, might help our current political situation feel slightly less sad and regressive. So let’s jump into the good news about why renewables are set to prevail no matter who’s at the helm.

Have you recently booked an Uber trip? There’s a chance the driver’s vehicle was an electric car, but Uber still has progress to make in that area.

To put things in perspective, 4 billion people took Uber trips in 2017, but only 4 million of those were in Uber electric cars.

The relatively few drivers who have electric vehicles (EVs) and work for Uber face challenges such as having difficulty finding charging points. In addition, the time it takes to recharge the cars interferes with time they could spend earning money.

National Aviation Day

On August 19, you can celebrate National Aviation Day. Perhaps you’ll do that by taking a flight to a place you’ve always wanted to explore, making good on your goal of signing up for flight lessons or just spending time feeling thankful we have that method of transportation at our disposal.

But, despite all the conveniences and innovations traveling by plane brings, it’s not kind to the environment. So, what can we do to start changing that bit by bit?

employment rates from agtech

We’ve all heard about how the robots are coming for our jobs. You’ve probably also heard about how wonderful automation is and how it can increase productivity and efficiency.

Agriculture is one of the many sectors in which automation is becoming more prevalent. Agricultural tech, known collectively as agtech, is transforming farming with its robots, sensors and algorithms.

The debate over whether the increasing rate of automation is a good or a bad thing is especially pronounced in agriculture. The sector has experienced job loss at the hands of technology before. It’s also facing extreme new challenges driven by a growing world population, an aging workforce and environmental changes.
