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  Compared the sets of data by finding the correlation between them and there detrended values

Background Information Cooling 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

Compared Data Temperature Correlation Electricity total consumption.51 Residual fuel oil total consumption -.20 Natural gas total consumption.29 Cooling degree days Electricity total consumption.38 Residual fuel oil total consumption -.19 Natural gas total consumption.21 Heating degree days Electricity total consumption-.32 Residual fuel oil total consumption.06 Natural gas total consumption-.13 Sum of annual degree days Electricity total consumption-.14 Residual fuel oil total consumption -.04 Natural gas total consumption-.03

Normalized total for the last 30 years Temperature.06 Cooling degree days.14 Heating degree days.06 Sum of degree days.13 Normalized total for the last 20 years Temperature-.44 Cooling degree days.09 Heating degree days.59 Sum of degree days.71

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 years There 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%
