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

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

HISTORY OF SOLAR ENERGY Jake Tutorow Indiana Institute of Technology Fort Wayne‚ IN Abstract: The purpose of this paper is to explain the history of solar energy as well as the difficulties faced in acquiring government support and investments for infrastructure and technological gains. The history of solar energy is broken into five distinct categories: Earth energy‚ the ancient solar age‚ the modern solar age‚ solar in the 1950s‚ solar today‚ and agriculture. Earth energy focuses on the understanding

?SOLUTIONS TO CLIMATE CHANGE IN ALASKA? Scientists believe that a decrease of between 65% and 80% of carbon dioxide emissions is necessary to prevent the effects of global warming (?Carbon Dioxide?) and government taking actions to find solutions in Alaska. To create awareness the government has released new climate data‚ tools‚ and mapping of Alaska that will assist them to understand and prepare for future climate change (Wuebbles and Jain 2001 p. 99-102). Permafrost has been a major problem in

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

Sustainability Assignment 1. What are the issues surrounding the idea that landfills are closing? Please discuss issues in terms of perceptions‚ reality‚ circumstances‚ and functionality. There are several issues surrounding the idea of landfills closing. There exists the idea that landfills have been closing at a rate that would not allow for the proper disposal of trash. However‚ the case of landfills closing is much more complicated than an initial glance at the data may seem. First‚ it was

is that the world only has so much oil and eventually we will run out. It’s common sense‚ a linear system can not work on a planet with finite resources. Since than several groups of forward thinking engineers and scientists have been working towards new ways to generate power without the use of oil. There have been several inventions that have been found to be great forms of renewable energy‚ which will minimize the use of oil. But what if we cut out the main use of oil consumption? The gasoline
