Hydrogen could serve as a viable alternative to fossil fuels that can be used directly as a fuel or can be used to generate electricity to power cars and other devices. However, large-scale production of hydrogen currently relies on fossil fuels and creates carbon emissions in the process. So-called green hydrogen involves using electricity to split […]

Tidal range electricity generation uses the water level difference between high and low tides to operate generator turbines.  The method requires the construction of barrages and sluices to capture water during high tides and then release it during generation at low tide.  Tidal range generation is predictable renewable energy driven by the gravitational pull of […]

There has been lots of turbulence in the electric car industry of late.  Part of it is aggressive publicity campaigns spreading misinformation and part of it is the natural fits and starts associated with major change.  But apart from the ups and downs of individual companies and countries, analysts are projecting another record year for […]

For years, we have heard that the iconic monarch butterfly is in great peril.  Monarchs east of the Rocky Mountains undertake a 4-generation, 3,000-mile migration in late summer to their winter home in central Mexico.  Since the 1990s, the overwintering monarch colonies began a steep decline causing scientists to fear for the sustainability of the […]

Scientists have been sounding the alarm on the global struggle of pollinators for a long time.  According to the United Nations, nearly 35% of the invertebrate pollinator species, such as bees and butterflies, are facing extinction. And since 75% of the world’s food crops depend on pollination to some extent, the decline of pollinators poses […]

American greenhouse gas emissions in 2023 fell by 1.9%.  In total, U.S. emissions have now fallen by over 17% since 2005.  The largest factor in the decline has been the reduction in the burning of coal to produce electricity.  Coal-fired generation has fallen to its lowest level in half a century. There was a huge […]

Standing up to 13 feet tall and weighing up to 7 tons, African savanna elephants are the largest species of elephant and the biggest terrestrial animal on Earth.  According to the World Wildlife Fund, African savanna elephants can be found in 23 countries and live in a variety of habitats, including savannas, forests, and deserts.  […]

Two up-and-coming energy technologies are coming together near a tiny town in central Utah.  Outside of the town of Delta, population 3,600, two caverns, each as deep as the Empire State Building, are being created from an underground salt formation to be used to store hydrogen gas.  The gas will be used as a fuel […]

Five separate weather-tracking organizations have proclaimed 2023 as the hottest year on record. They all agreed that 2023 beat the previous record-holder – 2016 – by a wide margin.  Organizations that use a pre-industrial baseline of 1850-1900 found that 2023 was 1.45 to 1.48 degrees Celsius above the baseline.  But what caused 2023 – especially […]

On January 2nd, the first large offshore wind farm in New England started producing electricity when its first turbine came online.  The Vineyard Wind project, located off the coast of Martha’s Vineyard, will by the end of the year have a total of 62 turbines with a capacity of 800 megawatts, enough electricity to power […]
