Electric cars: Boom or bust?

Earth Wise ·

2024/09/25

Media coverage of electric cars in this country is pretty confusing. Are electric cars taking over or has the EV bubble burst? EVs currently represent about 8% of the US new car market. But they continue to face some relatively unique headwinds in this country. A very powerful and influential oil industry makes sure that […]

Cities and rainwater

Earth Wise ·

2024/09/24

Cities across the country are grappling with the problem that bigger, more frequent rainstorms occurring as a result of climate change are overtaxing the systems put in place to handle stormwater. Cities use a combination of so-called green infrastructure – such as rain gardens and porous pavements – and traditional gray infrastructure, such as pipes, […]

Big Tech and emissions

Earth Wise ·

2024/09/23

Most of the well-known largest technology companies have established ambitious clean energy goals. They are on record for achieving net-zero emissions for all their operations and supply chains in many cases by 2030. As a result, they have been investing heavily in renewable energy in various ways. Despite these lofty goals and sincere efforts, many […]

Just say ‘climate change’

Earth Wise ·

2024/09/20

In recent years, climate advocates have pushed for the use of more dramatic language to describe ‘climate change.’ The notion was that phrases like ‘climate crisis’ and ‘climate emergency’ better convey the urgency of the planet’s plight, while terms like ‘climate change’ and ‘global warming’ are too gentle and vague. However, it turns out that […]

Solid-state batteries for cars

Earth Wise ·

2024/09/19

Battery-powered electric vehicles have historically faced the challenges of limited driving range and long charging time. In recent years, both of these limitations have been largely overcome for many if not most drivers. Popular EVs on the market can go 300 miles and more on a charge and today’s fastest charging networks can add 200 […]

A better way to produce green hydrogen

Earth Wise ·

2024/09/09

Hydrogen has great potential as a fuel and an energy carrier for many applications. Burning it or consuming it in fuel cells does not produce carbon emissions. As a result, there has long been the vision for a future hydrogen economy. Whether the hydrogen economy would ever come about given how various other technologies have […]

Less coal for making steel

Earth Wise ·

2024/09/05

Steel is primarily produced using one of two methods: blast furnaces or electric arc furnaces. The first blast furnaces were built in the 14th century. Making steel in a blast furnace starts by melting the raw materials of iron ore, limestone, and coal at very high temperatures. The resultant reactions ultimately lead to two products: […]

Emissions and the Great Salt Lake

Earth Wise ·

2024/09/04

The Great Salt Lake in Utah has been described as a puddle of its former self. The lake’s size fluctuates naturally with seasonal and long-term weather patterns, but the lake has been experiencing decline for decades as Utahans take water out of the rivers and streams that once fed the lake. Over recent decades, the […]

Where do states get their electricity?

Earth Wise ·

2024/09/03

How the United States produces its electricity has changed dramatically over the past few decades. Coal used to be the dominant source of power in this country, but natural gas surpassed it in 2016, and coal’s share has been shrinking ever since. Fossil fuel still generates the majority of America’s electricity, but renewable power is […]

Cooling cities

Earth Wise ·

2024/09/02

As the climate warms, city dwellers tend to suffer from extreme heat more than people in rural areas because of the urban heat island effect. Extensive surfaces of man-made materials like concrete, asphalt, and brick absorb the sun’s energy and lead to temperatures well above those in the surrounding countryside. Cities can take countermeasures that […]

One of the country’s largest co-located solar and battery energy storage projects is now fully operational. The Gemini Solar+Storage project is located in Clark County, Nevada, about 30 minutes outside of Las Vegas. The project’s 1.8 million solar panels can generate up to 690 megawatts of electricity, which is enough to supply about 10% of […]

China and carbon emissions

Earth Wise ·

2024/08/22

China has been the biggest source of greenhouse emissions for nearly 20 years. Its emissions surpassed those of the United States in 2006 and its fraction of the world’s emissions is now nearly a third. Therefore, unless China’s emissions stop growing, the world’s emissions won’t either. Recent data from China’s government and by energy analysts […]

Deep sea mining

Earth Wise ·

2024/08/19

Deep sea mining is the extraction of minerals from the ocean floor at depths greater than 660 feet and as much as 21,000 feet below the surface. Active or extinct hydrothermal vents on the ocean floor create sulfide deposits which collect metals such as silver, gold, copper, manganese, cobalt, and zinc. This forms polymetallic nodules […]

Industrial agriculture and the risk of pandemics

Earth Wise ·

2024/08/16

The domestication of pigs, cows, chickens, and other animals as livestock for their meat, milk, and eggs was historically revolutionary. It boosted food security by giving people a readily-available means of feeding themselves as opposed to more traditional methods such as hunting and fishing. But the industrialization of agriculture has led to horrendous conditions for […]

Increasing plastic recycling

Earth Wise ·

2024/08/15

Recycling plastic is a complicated matter. There are many different types of plastic and knowing which things are made of which type isn’t easy. There are increasingly widespread recycling systems across the U.S., but the actual rates of recycling have been described as “abysmal”. The plastic commonly used in beverage bottles is polyethylene terephthalate, or […]
