New York Offshore Wind

September 18, 2019 By EarthWise Leave a Comment

New York has passed ambitious legislation to reduce the carbon emissions that cause climate change, but the state needs to start taking action to make those reductions possible.  One such action it has taken is an agreement that will enable the construction of two large offshore wind projects.

The projects are to be built off the coast of Long Island.  One will be 14 miles south of Jones Beach and the other 30 miles north of Montauk.  The wind farms will be built by a division of Equinor, a major Danish energy company, and a joint venture between Orsted, another Danish company, and Eversource Energy, an American firm.

The two New York wind farms are expected to be operational within the next five years and have the capacity to produce 1,700 megawatts of electricity.  That is about 20% of Governor Andrew Cuomo’s overall goal for offshore wind.

Wind farms are a major energy source in the United States, now providing about 7% of the country’s electricity.  That compares with only 2% in 2010. But nearly all American wind turbines are on land.  There is only one small offshore wind farm in the US off the coast of Rhode Island.  Things are very different in Europe.  For example, Britain expects to get 10% of its electricity from offshore wind next year, which is up from less than 1% in 2010.

Developers of offshore wind farms have struggled to gain a foothold in the US.  Some projects have foundered because of cost issues, but others have faced opposition from politicians and coastal-property owners.  But assuming the New York wind projects clear permitting and environmental hurdles, offshore wind may finally be on the move in the US.

Sunlight As A Cash Crop

July 10, 2019 By EarthWise Leave a Comment

It isn’t so easy to be a farmer these days.  Farming has always involved long hours, hard work and the uncertainties of weather and yield.  The 21st Century has added new and unique challenges such as increasingly unpredictable weather, insect infestation and disease, and low commodity prices.  Add in sudden tariffs and farmers struggle even more to make ends meet.  The default rate for farmers’ loans is the the highest in at least nine years.

One thing that remains reliable for farmers is the sun.  It rises in the morning and goes down at night.  The sun can be trusted, unlike politicians, rain, or commodity prices.  These days, many farmers are taking advantage of the dependability of the sun to make money from a new cash crop: solar energy.

The trend is spreading.  North Carolina has been a leading solar energy state for several years and a 2017 report found that solar energy generates 30% of the income of many farms.  Typical annual rent payments for farmland by solar companies range from $500 to $1,400 per acre in North Carolina.

A growing list of states have clean energy mandates targeting 100% use of renewable energy.   These mandates provide incentives for farmers that make installing solar a financially smart decision and falling prices for solar installations make it an even better deal.

Solar works well when co-located on a farm and can be built in ways that minimizes impact.  It is quiet, uses almost no water, doesn’t pollute, and if it is decommissioned, the land can go back to its previous use.  If the solar facilities are raised up, the same land can be used to graze livestock or grow shade-tolerant crops.

Carbon Dioxide Marches On

The end of 2013 marked the first occasional observations of carbon dioxide levels in the atmosphere of 400 parts per million.  There is nothing magical about that value, but we do tend to focus on round numbers.

Clean Coal For Real

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.

The Hottest Year

2015 was the hottest year in the historical record, easily breaking the mark set only one year earlier.  The unusually large El Niño weather pattern is releasing enormous amounts of heat from the Pacific Ocean into the atmosphere, but climate scientists say that the bulk of the record-setting heat is due to the long-term warming effects of greenhouse gas emissions.  The global land surface temperature was 1.6°F above the 20th century historical average. That’s a huge jump from 2014, which was 1.3° above average.  That may sound like very little, but for the planet as a whole, it is extremely large.
