Insects On The Menu | Earth Wise

By Leave a Comment

According to the World Food Programme, a record 349 million people across 79 countries are facing acute food insecurity.  This constitutes a staggering rise of 200 million people compared to pre-pandemic levels.  Nearly one million people globally are fighting to survive in famine-like conditions, which is ten times more people than just five years ago.  

As a result, many experts contend that alternative or so-called novel food sources – such as lab-grown meats, seaweed aquaculture, and insects – will be necessary to help fight global hunger and global food insecurity. 

Insects already form a significant part of diets in many cultures around the world.  Insects are great sources of nutrients, including protein, vitamins, and minerals.  But insects have yet to be embraced in any substantial way in western cultures… but that may be changing. 

In fact, the European Union has now certified four types of bugs as food fit for human consumption.  The larvae of lesser mealworms and house crickets recently became the third and fourth insects approved for sale as food in the EU, joining yellow mealworms and grasshoppers. Eight more applications are awaiting approval.

Insects are already a delicacy in many high-end restaurants around the world, and a normal and healthy part of diets in countries like Mexico and Thailand.  Embracing insects as a food of the future will not only help in the fight against global hunger, but will also help to reduce greenhouse gas emissions and to slow species extinction. 

In Western food markets, the so-called “yuck factor” remains the biggest hurdle to cross.  But as the world population grows, the need for sustainable solutions in the food industry grows with it.

Banning Gas-Powered Cars | Earth Wise

By Leave a Comment

In June, the European Union voted to ban the sale of new gas- and diesel-powered vehicles starting in 2035.   The EU joined Canada, the United Kingdom, Japan, South Korea, and several other countries in imposing future gas car bans.

Here in the U.S., on August 25th, California adopted rules banning the sales of new gas-powered cars and light trucks by 2035.  New York passed a similar law last year and its ban will also cover heavy trucks by 2045.

California’s action is particularly significant because there are other states that have trigger laws that impose their own bans based on what California does.  Washington state, Massachusetts, and Virginia are in this category, although the governor of Virginia has said he plans to try to repeal the law.

An additional 12 states have policies tied to California’s and are likely to adopt their own versions of the 2035 ban.  These are Colorado, Connecticut, Delaware, Maine, Maryland, New Jersey, New Mexico, Nevada, Oregon, Pennsylvania, Rhode Island, and Vermont.

When these regulatory actions are coupled with the major investments in electric vehicles being made by virtually all automakers, the transition to electric vehicles appears to be inevitable.

As far as people who love their gas-powered cars are concerned, the new rules only apply to new car sales.  So, consumers can still buy and own used cars that run on gasoline.  If there are states that never impose bans on new gas-powered vehicles, then consumers can go to those states and buy one, assuming there are any being made at that point.   It seems likely that gas-powered cars will end up being made for hobbyists and aficionados only.

Continued Renewables Growth | Earth Wise

By Leave a Comment

In 2021, the world added a record amount of 295 gigawatts of renewable power.  According to the International Energy Agency, it is on pace to surpass that amount in 2022.

Almost half of the renewable buildout in the world is taking place in China.  In 2021, China accounted for 46% of worldwide renewable energy additions.  The EU and United States are the next two leaders.  The rapid buildup is especially impressive given the challenges developers have faced from the coronavirus pandemic, supply chain issues, and various construction delays.

Predictions are that the global total added this year will be about 320 gigawatts of renewables.  This amount is equivalent to the total power demands of Germany, which is the world’s fourth-largest economy.  Solar photovoltaics are forecast to account for 60% of the increase in global renewable capacity this year. 

The rapid growth in China and the EU are driven by strong pro-renewable policies.  In our country, wrangling over climate legislation and investigations into potential trade violations by Asian suppliers have held back our progress.  But over the next several years, offshore wind will begin to have a real impact on U.S. renewable installations.

According to the report by the International Energy Agency, renewable energy growth is likely to plateau in 2023 unless stronger climate policies are enacted. 

There are now more than 3 terawatts – that’s 3,000 gigawatts – of renewable generation capacity globally.  This compares with a little over 4,000 terawatts of fossil fuel generation.  Global renewable energy generation is currently projected to surpass that of fossil fuels by 2035.

A Big Year For European Solar Power | Earth Wise

By Leave a Comment

The installed solar capacity in the European Union grew by 34% in 2021.  This means that Europe is on pace to quadruple its solar energy generation by 2030.

During 2021, the 27 countries of the European Union installed 25.9 gigawatts of new solar capacity, compared with 19.3 gigawatts in 2020.  This was the biggest year yet for solar growth, beating out the previous record of 21.4 gigawatts set in 2011.  A gigawatt of solar electricity is enough to power about 300,000 homes, so the 2021 installations can produce enough electricity for about 8 million households.  The European Union is home to about 450 million people.

SolarPower Europe, an industry trade organization, projects that solar energy capacity in the EU will increase from the current 165 gigawatts to 328 gigawatts in 2025 and as much as 672 gigawatts by 2030.

The EU has the goal of generating 45% of its electricity from renewable sources by 2030, which is an important milestone in achieving climate neutrality by 2050. 

Challenges still facing the EU include obstacles to permitting, electricity grid bottlenecks, and assurance of solar panel supplies.  Much of Europe’s supply of solar panels comes from China.  The EU wants to boost its own production of solar panels to 20 gigawatts per year by 2025.

The US currently has about 113 GW of installed solar capacity and is projected to install about 300 gigawatts of new capacity over the next 10 years.

The Most Powerful Tidal Turbine Is Generating Power | Earth Wise

By Leave a Comment

The movement of waves, tides, and currents in the ocean carry enormous amounts of energy that in principle could be harnessed and converted into electricity to help power our homes, buildings, and cities.  Oceans cover nearly three-quarters of our planet, and the most populated areas of the world are located near oceans.

Ocean energy technologies lag far behind solar and wind power and remain mostly undeveloped.  This is a result of the unique challenges standing in the way of widespread deployment.  There are the considerable expenses of early-stage development, the wide variety of technical approaches from which winning strategies have yet to emerge, and the substantial challenges of operating in the ocean environment that include the physical impact of waves and tides, powerful and unpredictable weather, and corrosion and bio-fouling from the ocean and its inhabitants.

Despite these challenges, there is ongoing progress on ocean energy.   The world’s most powerful tidal turbine has come online this past April.  Known as the Orbital O2, the floating turbine is anchored in Scotland’s Fall of Warness, where a subsea cable connects it to the European Marine Energy Center.

The turbine produces enough electricity to meet the demand of about 2,000 homes in the UK.  It is expected to operate for the next 15 years.

Built by the Scottish engineering company Orbital Marine, the O2 was financed by the ethical investment platform Abundance Investment as well as being supported by the Scottish government and the European Union.   Orbital Marine’s goal is to commercialize this technology to play a role in tackling climate change using this new green energy technology.

Takeout Food And Ocean Litter | Earth Wise

By Leave a Comment

The Covid-19 pandemic saw most of us making use of take-out or delivery services as our only access to restaurant food.  It was a valuable link to normal life.  But unfortunately, the packaging of takeout food is a major contributor to the global plastic waste problem that isn’t going to disappear just because people are returning to eating in restaurants.

A new analysis of more than 12 million items by UK researchers published in the journal Nature Sustainability has found that the majority of ocean litter collected around the world is in the form of takeout food items:  bags, wrappers, containers, straws and cutlery, aluminum cans, and plastic and glass bottles.  Eighty percent of all the items surveyed were made of plastic.

Wrappers and packaging tended to concentrate along coasts, gathering on the shore and the sea floor.  Takeout trash was rarer in the open ocean.  In those areas, fishing debris accounted for half of the litter.

The authors of the study argue that efforts to curb plastic waste should prioritize takeout food and beverage containers.  They recommend that avoidable takeout items, like single-use plastic bags, should be replaced with non-plastic and biodegradable materials.  The authors also recommended making plastic producers responsible for the collection and disposal of plastic products.

As of July 1, the European Union has banned the 10 most common plastic and Stryofoam products found on European beaches.  The EU is also establishing an active European market for recycled plastics based on the principles of extended producer responsibility.

Global Warming Could Stabilize | Earth Wise

By Leave a Comment

The world has been heading toward climate disaster with the effects of greenhouse gas-induced warming looming larger and larger.  But recent analysis published in Nature Climate Change offers hope that rapidly eliminating emissions could stabilize global temperatures just within a couple of decades.

For quite some time, it has been assumed that further global warming would be locked in for generations regardless of the extent of emissions reductions going forward.  This conclusion was based on having a certain carbon dioxide concentration in the atmosphere which would linger for hundreds of years even if emissions were reduced.

Recent analysis takes into account the dynamism of the Earth’s natural systems which could actually reduce atmospheric CO2 content because of the huge carbon absorption capacity of oceans, wetlands, and forests.  The key requirement is to drastically reduce emissions so that these natural systems can take over.

More than 100 countries have pledged to get to net zero emissions by 2050.  That means they will emit no more carbon dioxide than is removed from the atmosphere by such actions as restoring forests.   The UK, Japan, and the European Union are among the countries that have set this zero target, and the United States is joining the club.

Climate models show that a global temperature rise of 2 degrees Celsius over that of the pre-industrial period would lead to global calamities that include punishing heatwaves, flooding, and mass displacement of people.  The world has already heated up by 1.1 degrees and governments have committed to restrain the rise to less than 1.5 degrees under the Paris Climate Agreement.

Europe’s Green Deal: Bad For The Planet? | Earth Wise

By Leave a Comment

In 2019, the European Union announced the “Green Deal,” a comprehensive program aimed at making Europe the first climate-neutral continent, implementing environmentally friendly transport, increasing recycling, and expanding renewable energy.

The Green Deal involves significant changes to European agriculture.  Over the next ten years, under the ambitious environmental program, at least a quarter of all agricultural areas will be farmed organically, the use of fertilizers and pesticides greatly reduced, 3 billion trees planted, 15,000 miles of rivers restored, and the population declines of pollinators reversed.

However, in a recent article published in Nature, scientists at the Karlsruhe Institute of Technology show that this Green Deal might actually be a bad deal for the planet.

The problem is that the EU is likely to basically be outsourcing environmental damage by its high imports of agricultural products.

According to the Karlsruhe study, the EU annually imports millions of tons of agricultural products, as much as 20% of its produce and much of its meat and dairy products.  Quite often, these imports come from countries whose environmental laws are far less stringent than those in Europe.

The EU cannot impose environmental standards on other countries, but it can demand that goods entering the European market meet EU requirements.  The study points out that Europe’s carbon footprint has to be evaluated on a global basis.  If the EU is truly to become a climate-neutral continent, it must include foreign trade goals and requirements in its environmental programs.  Otherwise, Europe will simply be outsourcing its environmental problems and will continue to cause damage to the planet.

Is It Time to Ban Neonics?

By Leave a Comment

Neonicotinoids (or ‘neonics’ for short) are a class of insecticides chemically related to nicotine.  In fact, the name ‘neonicotinoid’ literally means “new nicotine-like insecticide.”  And like nicotine, neonics act on certain kinds of receptors in the nerve synapse.  Most corn, soy, and wheat seeds planted today are coated with neonics, which is reportedly 5,000 to 10,000 times more toxic than DDT.

A Carbon Loophole

By Leave a Comment

Many power plants in Europe and elsewhere are replacing coal with wood.  For example, the Drax Power Station in Britain was its largest coal-burning plant and is now using wood pellets shipped from the southern U.S. in its boilers.    According to the carbon accounting rules at the EU and elsewhere, the process is considered to be “carbon neutral.”   But is it?

The idea is that new trees are being planted in the forests where the trees are cut to be burned in power plants.  So, there is carbon neutrality.  In principle.

European countries have embarked on a massive effort to switch to generating power from renewable energy.  While there has indeed been major growth in wind and solar power in the 28 countries of the European Union, much of the new “green” power has come from burning wood in converted coal power stations.

A group of 200 scientists wrote to the EU last September insisting that bioenergy from forest biomass is not carbon neutral and that there must be tighter rules to protect forests and their carbon.  Wood burning has become a loophole in controlling carbon emissions.

There are problems with the claims of carbon neutrality.  There is no way to know whether enough new trees are actually being planted to replace those being burned.  And then there is the time lag for tree replacement.  Trees don’t grow overnight.  There are also the carbon emissions associated with harvesting, processing and transporting wood.

There are most certainly ways in which burning biomass can be carbon neutral and can represent real progress over the use of fossil fuels.  But caution must be taken to avoid exploiting loopholes in current climate rules that might actually result in increased carbon emissions.

Offshore Wind In Europe

By

The U.S. has just turned on its first offshore wind farm off the coast of Rhode Island.  In the meantime, offshore wind continues to grow by leaps and bounds in Europe.   Wind energy in the European Union accounts for 12% of its electricity supply.  Until 2011, offshore wind comprised only 5-10% of the newly-installed wind energy capacity; now it about one third of the new installations.
