Energy consumption

Impact of CO2 emissions on usage of alternative energy

Overview


  • More people more consumption
  • More consumption of energy more CO2 emission
  • More CO2 emission

RISING POPULATIONLatin America


1971    176.19
1975    203.67 Millions

1988    303.91 Millions

2000 403.74 Millions

2009          468.71 Millions

Energy consumption


1971   497.27 KWh per capita

1980 881.37 KWh per capita
Over 3X 1971
1995 1336.82 KWh per capita

2009  1871.50

CO2 Emissions

1971     1.85 ton per capita
1980         2.45 tons per capita
1990                2.30 tons per capita

2009  2.77 tons per capita

More people however, the levels raised by 0.92
about 50%

So what's changed?

More efficient equipment
Technology evolution

Alternative and Nuclear Energy:

1971       3.17 % of total energy use

2009   10.16 % of total energy use
3x more than 1971

Quick stats


Consumption increased 3x since 1971
Population raised 3x since 1971
Alternative and Nuclear energy use increased 3x since 1971

CO2 emissions increased 50%

So, what?

Can we predict the usage of alternate energy?


Yes.
Well, kind of.....

3. Method of Analysis
Multiple Regression, Durbin-Watson Statistic

CO2 Emissions and Population

Population


Looks too good

Population quick stats


Energy Consumption and population
87.6% of data is described by the model
more we consume more CO2
indeed
82.9% is described by the linear regression between population and CO2 emission

Mean and median is really close (2.38 and 2.37)
IRQ (0.345)

Looks pretty good. are there any outliers?

Predictions

We would like to know whether CO2 has effect on usage of Alternative Energy


H0 hypothesis - Alternative Energy does not increase with CO2  emission increase.

Overall formula




Alt. Usg.= 8.24 - 4.25 * CO2 Emission + 0.00600 * Energy Consumption + 0.0080 * Population

Why is it important?

What does it mean for our data set?

What do we need to do?

What is that mean?


CO2 Emissions

might not directly caused by increase of

Alternative Energy Usage ,
but as consequence of policies and human common sense
