Mcguinty’s legacy is a green nightmare By Margret Wente‚ The globe and Mail‚ February 2‚ 2013 As our population grows and our society advances‚ there will be an increase in the demand of readily available energy. Fossil fuel based energy sources are costly‚ non-renewable and cause pollution‚ however wind energy has become the potential solution for all of our energy problems‚ or so we thought. McGuinty’s legacy is a green nightmare‚ by Margret Wente of the Globe and Mail explains that wind power

Conservation of Energy In explaining the laws of conservation of energy‚ energy cannot be destroyed or made. Although‚ energy can be transformed or transferred from one form to another‚ for example: The total amount of energy in any system never changes but stays constant over time. Second example: Coal is burned‚ and then used as thermal energy for heat‚ next the steam is used for mechanical energy. Energy is never destroyed but changed to forms like thermal energy‚ gravitational energy‚ electromagnetic

Organic cotton was introduced to the brand in 2004 in order to reduce negative environmental impact and to improve farmers’ conditions. The World Wildlife Fund (WWF) conducted studies that showed how organic cotton reduces pesticide usage by 32-81%‚ saves water by 32-49% and increases net profit for farmers by 15-20%. H&M is now the

A “Greener” Future: Myth or a Reality? With the accelerating pace of the technological boom‚ the need for an efficient and practical use of Earth’s resources has astronomically increased. Traditional manipulations of fossil fuels represent an arduous and taxing means for producing energy to power further innovation. Therefore‚ novel methods of energy production are requisite to future technological progress. Therefore‚ investments into sources of renewable energy have expanded yet have met

elements which make up the total of an typical person’s carbon footprint in the developed world. A carbon footprint is made up of the sum of two parts‚ the primary footprint (shown by the green slices of the pie chart) and the secondary footprint (shown as the yellow slices). 1. The primary footprint is a measure of our direct emissions of CO2 from the burning of fossil fuels including domestic energy consumption and transportation (e.g. car and plane). We have direct control of these. 2. The secondary
