Recycling conserves energy and resources. Market changes affect recycling opportunities. From time to time we have invested in metal, paper and cardboard, as well as recycling process equipment.
Concern for preserving timberlands and endangered species has reduced timber
harvests. Companies in which we seek investment produce paper boxes by recycling
the “urban forest” of waste paper.
We invest in companies which focus on organically grown, healthy food and pesticide-free products.
When we find suitable opportunities, we may invest in batteries for electric vehicles, railroads, bicycles, canoes and kayaks, the use of which serve to reduce pollution and save energy.
We may invest in water related companies which provide clean potable water, sewerage treatment, filtration equipment, equipment for energy efficient water distribution, and/or development of reverse osmosis to make salt water potable.
Renewable energy and energy conservation serve to maintain clean air and a natural environment.
Natural gas is the cleanest hydrocarbon fuel. It is often used for heating and for efficient combined heat, air conditioning and electric power generation. It is sometimes used for peaking to balance the load on the electric grid.
There are environmental concerns about natural gas extraction by hydraulic fracturing and carbon emissions from methane leaks. We may invest in natural gas distribution utilities or companies which use natural gas for cogeneration, combined heat and power, or to produce hydrogen or power fuel cells.
