Renewable Energy

Renewable energy flows involve natural phenomena such as sunlight, wind, tides, plant growth, and geothermal heat, as the International Energy Agency explains:

Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.

Renewable energy resources and significant opportunities for energy efficiency exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency, and technological diversification of energy sources, would result in significant energy security and economic benefits.

Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services:

  • Wind Energy

  • Wind & Solar Energy

  • Solar Energy

Power generation. Renewable energy provides 19% of electricity generation worldwide. Renewable power generators are spread across many countries, and wind power alone already provides a significant share of electricity in some areas: for example, 14% in the U.S. state of Iowa, 40% in the northern German state of Schleswig-Holstein, and 20% in Denmark. Some countries get most of their power from renewables, including Iceland (100%), Norway (98%), Brazil (86%), Austria (62%), New Zealand (65%), and Sweden (54%).

Heating. Solar hot water makes an important contribution to renewable heat in many countries, most notably in China, which now has 70% of the global total (180 GWth). Most of these systems are installed on multi-family apartment buildings and meet a portion of the hot water needs of an estimated 50–60 million households in China. Worldwide, total installed solar water heating systems meet a portion of the water heating needs of over 70 million households. The use of biomass for heating continues to grow as well. In Sweden, national use of biomass energy has surpassed that of oil. Direct geothermal for heating is also growing rapidly.

Transport fuels. Renewable biofuels have contributed to a significant decline in oil consumption in the United States since 2006.The 93 billion liters of biofuels produced worldwide in 2009 displaced the equivalent of an estimated 68 billion liters of gasoline, equal to about 5% of world gasoline production.

In international public opinion surveys there is strong support for promoting renewable sources such as solar power and wind power, requiring utilities to use more renewable energy (even if this increases the cost), and providing tax incentives to encourage the development and use of such technologies. There is substantial optimism that renewable energy investments will pay off economically in the long term.




Wind Energy


About Small Wind

Small wind energy systems are one of the fastest growing forms of customer-sited or “distributed” electric generation and one of the best energy investments for small businesses and homeowners.

Small (or “residential”) wind energy systems typically generate just enough power to meet the demands of a home, farm or small business. They range from 400 watts to 500 kilowatts or more and typically consist of a single turbine (vertical or horizontal). They can be significant power sources and have proven records of performance, even in locations with modest winds.

The success of the commercial wind industry has propelled significant advances in small turbine design, making these systems more reliable, quieter and safer than those introduced in past decades. And though most of the electricity they produce is used on-site, excess generation can be fed into distribution lines, strengthening the electric grid.

 

Solar Energy


When we think green we usually think of solar energy. Solar energy is harnessed by converting sunlight into electricity. There are a couple of ways of converting sunlight into electricity. It can be directly converted using photovoltaics (PV), or indirectly with concentrating solar power (CSP).
