Wind Power Update | Earth Wise

October 8, 2021 By EarthWise Leave a Comment

The Department of Energy recently released three reports showing record growth in land-based wind energy, a growing number of offshore wind projects, and the continuing reduction in the cost of wind power.

The U.S. installed a record amount of land-based wind energy in 2020. In total, 16,836 MW of new utility-scale land-based wind power capacity was added during the year, representing $24.6 billion in new wind power projects. This was more added than from any other energy source and represented 42% of new U.S. energy capacity.

For the year, wind energy provided more than 10% of in-state electricity generation in 16 states. Notably, wind provided 57% of Iowa’s electricity and more than 30% in Kansas, Oklahoma, South Dakota, and North Dakota.

As wind turbines continue to grow in size and power, they are producing more energy at lower cost. Turbine prices have gone from $1,800/kW in 2008 to $770-850/kW now.

The pipeline for U.S. offshore wind energy projects has grown to 35,324 MW, a 24% increase over the previous year. The Bureau of Ocean Management created five new wind energy areas in the New York Bight with a total of 9,800 MW of capacity.

Distributed wind power, which are systems connected on the customer’s side of the power meter as opposed to those on the utility side, also saw increased growth last year.

Wind power is a key element in the adminstration’s goal of having a decarbonized electricity sector by 2035.

New Nutrition Labels

February 26, 2019 By EarthWise 1 Comment

Food and beverage packaging in this country has included a Nutrition Facts panel for nearly 25 years. Over 700,000 products have the labels which provide consumers with information like serving sizes, calories per serving, ingredients, and nutritional content.

Surveys indicate that 77 percent of all U.S. adults claim to use the labels at least some of the time. Whether the labels are actually useful is somewhat debatable. A couple of years ago, the FDA released a proposal to update the labels to make them more useful and to reflect more recent nutritional research. The new labels are finally going to be implemented and food manufacturers with annual sales exceeding $10 million have until January of 2020 to update their packaging with the new labels.

One of the biggest changes is that the “serving size” section of the label will be changed to more accurately reflect the actual portions consumed by the typical American. For example, a 20-ounce soft drink will now be labeled as a single serving because most people will drink the whole bottle in one sitting.

The new labels will no long list the amounts of Vitamin A and C, because recent research shows most Americans are not deficient in these nutrients. Instead, the amount of Vitamin D and potassium will be listed, two nutrients lacking in many diets. New labels will also show amounts of “added sugars”, defined as caloric sweeteners with no nutritional value. The new labels will also display the calories per serving in much large type making that piece of information far more noticeable.

There is surely more to be done to make food labeling more transparent and useful for consumers, but the new changes at least seem to be in the right direction.

A Big Problem For The Giant Panda

November 10, 2017 By EarthWise Leave a Comment

The giant panda, a national icon of China, has been the focus of an intensive, high-profile conservation campaign since the 1970s. In an update to the IUCN’s Red List of Threatened Species last year, the giant panda had its designation changed from “endangered” to “vulnerable” following a nationwide census that revealed its population was improving. But it appears as though this conservation success may be short-lived.

Pandas No Longer Endangered

Back in June, we reported that the International Union for the Conservation of Nature was reassessing the giant panda’s status as an endangered species. Well, in an update of the IUCN’s Red List of Threatened Species in September, the giant panda was indeed downgraded to “vulnerable.”
