Motivation

Helps energy companies save $$$ To help consumers see if they are paying more

money for the same amount of energy.

Research Questions How does climate effect trade?

How does temperature effect total energy consumption?

Hypothesis- Temperature accounts for 70% of total energy

consumption.

Methods and Data Annual Average temperature, Cooling degree days,

Heating degree days and Sum of degree days(NC State climate office)

Set of total energy consumption data with smaller sub sets of data (State energy Data System) from NC

○ ESTCP- Electricity total consumption

○ RFTCP- Residual fuel oil total consumption,

○ NGRCP-Natural gas total consumption

Years 1960-2009 Compared the sets of data by finding the correlation

between them and there detrended values

Background InformationCooling Degree days-CDD

Heating Degree days-HDD

Key HDD= heating degree days

CDD= cooling degree days

SADD= sum of annual degree days AV temp= average temperature

Fitted Total= normalized Energy consumption

Fitted ESTCP KKWH= Electricity Total Consumption

Discussion Temperature effects energy consumption by

about 50%The research rejected my hypothesized 70%

but supported the facet that it does have some affect

Didn’t account for other ways of heating and power such as… propane solar power wood burning wind power

If theses were taken into account how much of a difference would it make?

Future Research How does temperature effect agricultural trade? How do storms effect trade? How does the effect of temperature on energy trade

effect the price of energy? How do natural disasters effect agricultural trade? How do hurricanes effect the economy of the places

they hit? How does climate effect energy trade? How does climate effect energy consumption?

Approach

Total energy consumption and temperature correlated over 50, 30, and then 20 yearsThere seemed to be more of a pattern

during the last 30 years and the correlations for the most part increased

Since the 30 year period increased the correlations, I correlated the 20 year period

Results The research rejected my hypothesized 70% but

supported the facet that it does have some affect Temperature effects energy consumption by about

50%
