Question 1:

The recent slump in oil prices has raised questions about the prospects for alternative energy sources. However, in today’s global markets, the historic correlation between oil prices and the demand for alternative energy has been weakened by the fact that these two types of energy sources are used for totally different purposes. Oil is mainly used in transportation while alternative sources such as solar, biofuel and wind are used for electricity generation (Day, 2014). From basic economic principles, oil and alternative energy sources are not substitutes since a price decline of one does not constitute a subsequent decrease Continue reading...

Nature knows best. Humankind has fashioned technology to improve upon nature,
but such change in a natural system is likely to be detrimental to that system.

Introduction
London traffic problems are known all over the world, while travel time in a rush hour may increase dramatically. Rapid increase in London population has provoked an overall drastic shift from private transportation to public transport means, cycling and walking. Increase of public transport popularity has achieved 44% compared to 33% of public transport usage in 2012. Cycling is getting more popular in London with each year mainly due to extreme transportation Continue reading...

The average American spends $2000 annually on electricity. Energy cost in the United States varies from state to state. The average energy cost electricity is 11 cents per kilowatt hour (Hinch Par 1). This means that the annual energy consumption is:
$2000$0.11=18,181.81KWh

The average power generated by a 15% efficient, 4m2 panel will be given by:

15%*110*4=66W/panel

There are 8760 hours in a year, so total energy produced will be:

8,760h*66Wpanel=578,160Wh
A single panel will produce 578.16KWh per year.

The number of panels required to support annual energy requirements will be:

18,181.81578.16=31.44 panels
32 panels will be required
32*$800=$25,600

The annual energy bill is $2000. The time taken to recoup the initial investment in form of energy savings will be:

$25,600$2000=12.8years
The total incentives offered will be: $0.85*18,181.81=$15,454.54
Amount to be paid after incentives: 25,600-15,454.54=$10,145.46

Payback period after incentives:

10,145.462000=5.07 years
