Whom Should We Save?
The list of endangered species continues to get longer around the world and society is increasingly faced with the nearly impossible decision of which ones to take off life support.
Indirect Greenhouse Gas Emissions
When considering the greenhouse gas emissions associated with any energy source, it is important to look at the total life cycle emissions both from the direct use of the energy source and from the indirect emissions associated with building the system, producing and transporting fuels and other supplies and, ultimately, decommissioning the system. Taking all of this into consideration is necessary in order to have a full accounting of the carbon impact of power sources.
Fossil Fuel Companies And Renewables
There is a tendency to think of the changes in the energy industry as a pitched battle between fossil fuel companies and renewable energy. There is some truth to this, but only to a certain extent. The multi-trillion-dollar fossil fuel industry is made up of businesses dedicated to growth and increased profits. And like businesses in other industries when major changes occur, fossil fuel companies may read the tea leaves and change with the times.
A Helpful Invader
Invasive species are a great concern for the health and stability of ecosystems. They are defined as plants, animals or pathogens that are non-native to the ecosystem under consideration and whose introduction causes or is likely to cause harm. It is that latter consideration that isn’t always obvious.
Are Electric Cars Worth The Price?
Pretty much every discussion of electric cars, plug-in hybrids and ordinary hybrids starts and ends up with the question of whether they are worth the money. If the reason for buying such a vehicle is strictly economic, then this is the right question to ask. But the naysayers who say such a purchase is foolish may be barking up the wrong tree.
