The Future of “Clean” Energy

By Murray Rosenblith, Co-Manager, New Alternatives Fund


A recent article in Bloomberg New Energy Finance predicts that two-thirds of the world’s power will be generated by renewable resources by the year 2050. This projection is based on the continuing growth of new renewable power generation projects, primarily wind and solar, over the next thirty-plus years. Conditions have certainly changed since New Alternatives Fund entered the investment world in September 1982.

When New Alternatives began operation as the first mutual fund concentrating on what was generally called “alternative energy,” the sector was seen as a niche area. Socially responsible investing was still a relatively young concept. Investment professionals were still skeptical about the idea that principles, human values, the environment and other non-financial metrics factor in their business decisions. There were concerns about “energy security” growing out of the economic disruption caused by the OPEC oil boycott in 1973. In addition, there was a growing consensus that damage to the environment could have a negative effect on the general health of populations and economic growth.

The publication of Rachel Carson’s Silent Spring in 1962, which raised awareness of the damage that widespread pesticide use was causing, created a wider concern about water and air pollution. This sensibility eventually led the U.S. Congress to pass the Clean Air Act in 1963 and the Clean Water Act in 1972, mandating controls on waste materials that were being generated by mining, manufacturing and power generation and dumped in waterways and in the air. These laws also put limits on the amount of dangerous emissions from cars and other transportation. The Environmental Protection Agency (EPA), created under President Nixon in 1970, oversaw the enforcement of most of these regulations. But the broader concept of an emerging challenge of “climate change” was not generally part of the public consciousness as yet.

During this same period, however, the science and awareness of the larger issues involving carbon emissions and the long-term effects on the world environment were growing and would come to bear on how we viewed the total costs of energy. The United Nations Environment Programme (UNEP), starting in 1972, worked on providing support to countries around the world, with an emphasis on developing nations, to create energy plans based on systems that reduced the carbon emissions they produced. The UNEP would eventually create the Intergovernmental Panel on Climate Change (IPCC) in 1988, to provide scientific research on climate change causes and effects and promote wider introduction of clean energy production.

Hydropower for electric generation was well developed and broadly used. But solar power, in the form of photovoltaic cells and direct solar heating technology, was still mostly the province of “off grid” simple living pioneers and a few developing nations that lacked wider power infrastructure. Wind turbines were still relatively small scale, generating, on average, several hundred watts (kw) of electricity. In response to the 1973 oil crisis and the increased cost of oil and gas, the U.S. government increased funding for renewable energy research and development. As a result, more efficient and powerful turbines were designed and the first wind farms were created in the U.S. and Europe. But as late as 1981, one year before New Alternatives Fund opened, there were still only two wind farms in the U.S., generating about 10 megawatts (mw) of electricity, enough to power just over 8,500 homes. In the early 1980s, as oil and gas prices came down, solar and wind power development declined because they were now economically noncompetitive.

Governments around the world, primarily in Western Europe, Japan, South Korea, Canada and, to a lesser extent, the United States, began funding renewable energy development and enacting policies that supported the introduction of renewables into their power and transportation systems. New technologies, many with government support, improved the efficiency of wind and solar power systems, energy storage capacities and energy efficiency to the point where, today, most renewables can compete economically with fossil fuel energy generation. Considering the “externalities” of the existing power system and the growing concerns for the health and future of the world’s environment, renewable energy has emerged as the way forward. Or so it would seem if science and logic were universally applied.

New Alternatives Fund’s approach has always been to consider the broad sector of energy and related environmental areas like clean water, clean air, and naturally grown and organic food. Energy is not just the production of electric power. Conservation and efficiency play major roles in the future of the world’s energy. As populations grow and more people move to a higher standard of living, we will face greater energy demands. One of the most important trends in recent years has been the advancement of technologies that produce units of energy more efficiently, whether it is larger wind turbines being developed by Vestas Wind Systems of Denmark, more efficient solar modules from First Solar, lighting systems from Signify NV of The Netherlands or building energy management controls from Ingersoll-Rand PLC of Ireland. The ability to “do more with less” is an important aspect of the future of renewable energy.

But the path has, obviously, not been so straight. Human beings are not always rational actors. The entrenched economic interests of the existing power systems, coupled with the enormous expense involved with creating an entirely new structure for humanity’s growing power demands, has led to a back-and-forth struggle that does not always reward the renewable sector. Like any other commercial enterprise, not every company will be well run or necessarily develop a successful product. The push-back from more conservative political forces has, at times, caused a financial retreat from renewables. Fortunately, we have weathered these storms and continued the growth and development of what must ultimately be the energy of the future.

From 1985 to 2008, he served as Executive Director of the A.J. Muste Memorial Institute, a publicly funded charitable foundation which supported activist groups working for nonviolent social change. While at the Institute, he helped start and manage the endowment of an affiliated group and was a 20-year member of the Social Investment Forum. Prior to his position at the Muste Institute, he was an editor and business manager at WIN Magazine from 1974 to 1982. Murray has been an activist and organizer in social justice movements for over 40 years. He received a B.S. in Journalism from Boston University.
