As our global carbon dioxide emissions grow, they highlight the need for increased reliance on renewable energy sources. Its wealth of energy resources has made Canada the fifth-biggest energy producer in the world. Over 60 percent of oil produced is exported with most going to the United States since 1995. The positive statistics of renewable energy reveal Canada is using more in recent years.

The different renewable energy fields have variances in capacities. On the whole they offer benefits of negligible greenhouse gas emissions and a sustainable energy source. To protect our planet and our species we need more reliance on what is more sustainable over the long term.

Renewable energy sources supply about 16 percent of the energy needs of Canada. Water is the dominant source in this providing approximately 59 percent and about 11 percent of total supply from all energy sources. There are many rivers that flow from Canadian mountains to its three oceanic borders. In 2006, there were 499 hydroelectric stations that made this country the second largest producer of hydroelectricity in the world. Quebec, British Columbia, Ontario, Labrador and Manitoba are the major provinces active in this sector.

The next most dominant source is biomass with wood a leading material from this country rich in its forests. The paper and pulp industry is the largest user. By the beginning of 2007, there were over 60 bioenergy plants. Canada is a leading producer and exporter of wheat, corn and barley and they constitute the principal agriculture feedstock for producing ethanol. In 2006, the biofuel capacity for ethanol was near 600 million litres and for biodiesel a 100 million litres.

Wind use has risen. By 2008, there were eighty-five wind farms on which fourteen hundred wind turbines were established with installed capacity over eighteen hundred megawatts. This was a major step up from sixty wind turbines on just eight wind farms and a mere twenty three megawatts of capacity only ten years ago. The solar usage has also improved with an average annual rate of seventeen percent rise in solar thermal installations since the year 1998. Solar photovoltaic installations have also increased yearly by twenty seven percent since the year 1993. Over eighty percent of these installations are off the grid. Over three thousand geothermal heat pump units have been installed in different types of buildings by 2006.

The report of Eurostat for the year 2009 reveals further European applications. The report provides that renewable energy use grew by over eight percent. Coal use fell by over nine percent and natural gas use fell by over ten percent. Generally, total energy use fell by over five percent. Yet, for the six straight year the energy intensity declined to over eighteen percent in 2009.

With wind power leaders like Germany and Spain, Europe continues to advance. Germany has demonstrate that a country can go from negligible user to notable user with determination. The second biggest global solar market is in Germany. A solar cell production leader is also German. The German goal of reducing carbon emissions by over third by 2020 illustrates its commitment. The Portuguese use of almost forty five percent energy from renewable sources up from seventeen percent demonstrates why Europe has shown dramatic improvements in ten years. Examples like this fuel European progress, despite variances amongst the constituent parts.

In neighboring United States, the Department of Energy reports that three out of most recent four years has seen lowered emissions with 2009 setting a new bar. This has been due to both reduced usage and from switching to gas from coal. In both Europe and the United States there have been renewable energy installations exceeding those for fossil fuel in the previous year. However, with less than 20 percent of global power produced, renewable sources have to be relied on to a far greater extend. Thus, although the growing improvements in statistics of renewable energy are positive, but, there is still much room for additional improvements such as a continuous support for the Feed in Tariff program.

Solar Power devices, green energy and alternative energy sources like the field of science is around every day. The children learn with fun optical equipment, telescopes and science lab equipment.
