Renewable energy

Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). About 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass, which is mainly used for heating, and 3.4% from hydroelectricity.  New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 2.8% and are growing very rapidly. The share of renewables in electricity generation is around 19%, with 16% of global electricity coming from hydroelectricity and 3% from new renewables.

Wind power is growing at the rate of 30% annually, with a worldwide installed capacity of 198 gigawatts (GW) in 2010, and is widely used in Europe, Asia, and the United States. At the end of 2010, cumulative global photovoltaic (PV) installations surpassed 40 GW and PV power stations are popular in Germany and Spain. Solar thermal power stations operate in the USA and Spain, and the largest of these is the 354 megawatt (MW) SEGS power plant in the Mojave Desert. The world’s largest geothermal power installation is the Geysers in California, with a rated capacity of 750 MW. Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar cane, and ethanol now provides 18% of the country’s automotive fuel. Ethanol fuel is also widely available in the USA.

While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas, where energy is often crucial in human development. As of 2011, small solar PV systems provide electricity to a few million households, and micro-hydro configured into mini-grids serves many more. Over 44 million households use biogas made in household-scale digesters for lighting and/or cooking, and more than 166 million households rely on a new generation of more-efficient biomass cookstoves. United Nations’ Secretary-General Ban Ki-moon has said that renewable energy has the ability to lift the poorest nations to new levels of prosperity.

Investors regularly travel to the United States to monitor and assess developments in renewable energy. It is recommended that overseas visitors and scientists to the United States shop for flight tickets online compare quotes offered by Visitor Guard USA insurance coverage or simply enroll on the Atlas Insurance for Visitors.

You can find out more about renewable energy in the United States by visiting the US Department of Energy, and there are statistics and information available on the National Atlas page.

Investing In Renewable Energy

Why Invest in Renewable Energy?
Given all the attention that renewable energy is getting in the news over the last couple years, investing in renewable energy has become a hot topic. People are drawn to renewable energy for one of several reasons:

  • To fight Global Warming
  • To prepare for Peak Oil.
  • To improve Energy Security and local economies.
  • To cash in on the above trends.

The beauty of investing in renewable energy companies is that these goals are not mutually exclusive. With one investment, the investor can feel good about what his money is doing for three reasons, while putting his money in what is proving to be a spectacular growth story.

How To Invest

For mutual fund investors, Renewable Energy focused mutual funds have been few and far between, but the recent growth of interest in the sector has lead to a plethora of new offerings. US investors can choose from load funds such as the New Alternatives Fund (NALFX) and Calvert Global Alternative Energy Fund (CGAEX) and the no-load Guinness Atkinson Alternative Energy Fund (GAAEX). Unfortunately, the load funds have expense ratios in excess of 1.25%, and the Guinness Atkinson fund’s ratio is 1.98%. Given these high expenses, I strongly prefer the industry ETFs.

Worldwide efforts are under way for cutting carbon dioxide emissions. Recycling steel, aluminum and copper are a few examples of where the energy used to recycle these metals is minimal compared to the energy required produce them. Cars, appliances and other products are continually being redesigned to allow for easy disassembly into component parts for recycling or reuse.

Other countries such as Japan and Germany are requiring that automobiles, office equipment and household appliances be designed to allow for easier dis-assembly and recycling. Japan is mandating that consumers bear the cost of disassembling items such as washing machines, TV’s and air conditioners. In May of 1998 Japanese recycling law forbids discarding appliances without first disassembling them at the consumers expense.

The Caterpillar Company is a leader in the re-manufacturing of its heavy industry sector. At one plant in Corinth Mississippi, Caterpillar recycles 17 truckloads of diesel engines per day. The engines are dissembled by hand without throwing away a simple bolt or screw. All these parts are then repaired and eventually reassembled into a new engine. The company’s re-manufacturing division adds one billion dollars to its bottom line in the process!

Recycling Facts

The U. S. opened the first recycling center in 1896. Since that time we have come a long way. However, we still have a long way to go to improve the transformation of waste into useable resources.

How Much Trash is produced in the US?

Municipal solid waste (MSW) consists of common household trash such as food scraps. packaging, yard waste and appliances. The Environmental Protection Agency (EPA) takes all of these things into account when compiling statistics for MSW. These figures do not include construction waste or hazardous materials.

As the trash in the U.S. continues to increase, EPA Statistic show that from 1980 until 2005 MSW increased by 60% representing 246 million tons of MSW, hat figure is 2 million tons smaller than in 2004.
