Green Energy Solutions

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:



  • 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 and Paraguay (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.

Renewable Energy

Renewable energy is made from resources that Mother Nature will replace, like wind, water and sunshine. It is also being called “clean energy” or “green power” because it doesn’t pollute the air or the water. It a power source that is not limited, as fossil fuels are.

Renewable energy is considered a very important solution to a problem that has grown out of control worldwide. It has been determined to be a clean alternative energy source.

Renewable energy is ready for a global takeoff, and has become the answer for a better tomorrow.

Renewable energy is a broad category of sources that draws from the energy around us naturally. Renewable energy is seen as one of the important components of climate change solution. It is astounding that so much of the worlds fossil fuels have been depleted, and that renewable energy is just now be sought as a viable alternative.

Renewable energy is the main component of eco-energy planning. It is available in a variety of methods of use, which can reduce energy consumption, preclude energy utilization and eliminate our dependence on non-renewable energy sources.

Renewable energy is produced from continuously available natural processes that do not involve the consumption of exhaustible resources such as fossil fuels. Renewable energy is also called “clean energy” or “green power” because it doesn’t pollute the air or the water.

Renewable energy is used for electricity generation, heat in industrial processes, heating and cooling buildings, and transportation fuels. It is assisting America in meeting its energy needs. Renewable energy effectively utilizes natural resources such as sunlight, wind, tides and geothermal heat, which are naturally replenished. Renewable energy systems encompass a broad and diverse array of technologies, and the current status of these can vary considerably.

Renewable energy power generated from the nearly infinite elements of nature such as sunshine, wind, the movement of water, the internal heat of the Earth, and the combustion of replenishable crops is very popular with the public and governmental officials because it is an unlimited and environmentally gentle source of power, particularly compared with the supposedly limited and environmentally challenging alternative of reliance on fossil fuels and nuclear power.
