geoengineering explained: the advantages and disadvantages of ambient air capture

Ambient air capture, a form of carbon dioxide sequestration (CDR), involves building large machines that can remove carbon dioxide directly from the ambient air so that the captured CO2 can be stored elsewhere. The three steps of the air capture process are: Contacting the air Absorption or adsorption on a sorbent Recovery of the sorbent see also:…

geoengineering explained: the benefits and challenges of albedo enhancement

Albedo is the fraction of the sun’s radiation reflected from a surface. It is quantified as the proportion or percentage of solar radiation of all wavelengths reflected by a body or surface to the amount incident upon it. An ideal white body has an albedo of 100% and an ideal black body is 0%. Albedo…

geoengineering explained: the benefits and challenges of afforestation

Afforestation is the process of planting trees, or sowing seeds, in a barren land devoid of any trees to create a forest. The term should not be confused with reforestation, which is the process of specifically planting native trees into a forest that has decreasing numbers of trees. The increased number of trees helps to…

smart electric grids

smart electric grids

The current electric system in the United States is very inefficient due to congestion in the transmission lines. In turn, electricity is wasted and higher costs are passed onto consumers. A viable solution for this issue is creating a national electric grid.  This new grid is known as a Smart Grid.  Smart Grids allow for…

why is the world still so dependent on fossil fuels?

There is no doubt about it – fossil fuels still reign supreme. Industry and consumers are still slaves to this non-renewable resource despite the fact that it pollutes our environment and results in an inequitable distribution of wealth that is concentrated in the hands of a select group of people not necessarily concerned with the…
