- Demand driven by high oil prices, environmental concerns and government regulation.
- Competing alternative energy solutions and evolving technologies create several investment opportunities.
- Ways to invest with ETFs:
Progressive (bridge technologies):PUW
- Another option is to go with a socially responsible investing ETF.
The rising cost of existing energy sources combined with the growing environmental – global warming movement create increasing demand for clean energy.
According to the National Renewable Energy Lab, demand for renewable energy will continue to outstrip supply for the foreseeable future, despite projected capacity growth from 30 million MWh in 2006 to 85 million MWh by 2010.
One of the key drivers of demand is the fact that 25 states plus the District of Columbia have enacted renewable portfolio standards (RPS) requirements ranging from 2% to 30% of total electricity supply, to be achieved over the next five to 15 years.
At the same time, global demand for renewable energy equipment is already leading to supply shortages for wind turbines and photovoltaic modules.
Renewable Energy Basics
The United States currently relies heavily on coal, oil, and natural gas for its energy. Fossil fuels are nonrenewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources—such as wind and solar energy—are constantly replenished and will never run out.
Most renewable energy comes either directly or indirectly from the sun. Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses.
The sun’s heat also drives the winds, whose energy is captured with wind turbines. Then, the winds and the sun’s heat cause water to evaporate. When this water vapor turns into rain or snow and flows downhill into rivers or streams, its energy can be captured using hydropower.
Along with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called biomass energy.
Hydrogen also can be found in many organic compounds, as well as water. It’s the most abundant element on the Earth. But it doesn’t occur naturally as a gas. It’s always combined with other elements, such as with oxygen to make water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity.
Not all renewable energy resources come from the sun. Geothermal energy taps the Earth’s internal heat for a variety of uses, including electric power production, and the heating and cooling of buildings. And the energy of the ocean’s tides comes from the gravitational pull of the moon and the sun upon the Earth.
The ocean can produce thermal energy from the sun’s heat and mechanical energy from the tides and waves. NREL does not conduct research in ocean thermal energy or ocean mechanical energy. See the U.S. Department of Energy’s Consumer Guide Web site for basic information ocean energy.
Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower. NREL doesn’t perform any research in hydroelectric power technologies. For more information on hydroelectric power, see the Hydropower Basics from the U.S. Department of Energy’s Wind and Hydropower Technologies Program.
There are several ways to invest in clean energy with exchange traded funds.
The largest of the group is the $1.6 billion PowerShares WilderHill Clean Energy Portfolio (PBW) which tracks an index designed to deliver capital appreciation through the selection of companies that focus on greener and generally renewable sources of energy and technologies that facilitate cleaner energy.
Top holdings as of July 31 includeFuel Systems Solutions Inc.(FSYS), VeraSun Energy Corp.(VSE), FuelCell Energy Inc. (FCEL) and ReneSola Ltd (SOL).
PowerShares also offers the Global Clean Energy Portfolio (PBD) which is composed of companies that focus on greener and generally renewable sources of energy and technologies facilitating cleaner energy.
Van Eck sponors the Global Alternative Energy ETF (GEX)which owns 30 stocks with the highest average trading volume and market capitalization and are “principally engaged” in the business of alternative energy.
The modified equal weighted portfolio is rebalanced and reconstituted quarterly.
