Kane County Electricity Use (in kWh)

2007 Residential 1,664,588,247 C&I 3,271,827,251 Total 4,936,415,497 2008 Residential 1,617,248,849 C&I 3,253,629,099 Total 4,870,877,948 Percent change Residential

• 2.93%

C&I

• 0.56%

Total

• 1.35%

C&I 66% Residential 34%

% split of usage between Residential and C&I – consistent for 2007 and 2008

Slide 5

Potential reasons for changes in consumption from 2007 to 2008

Electricity: Decreased consumption

1) Weather: 2007 summer was hotter than 2008, based on number

• f cooling degree days (CDD)
• 2007: 1111 CDD
• 2008: 828 CDD
• 30 year average: 830 CDD.1

2) Economy

1 For the Chicago O’Hare weather station http://cdo.ncdc.noaa.gov/cgi-bin/climatenormals/climatenormals.pl

Example: How to calculate cooling degree days June 1, 2007: average temperature of 74°F Base temperature of a building: 65°F Number of cooling degree days: 74 – 65 = 9

Slide 7

Potential reasons for changes in consumption from 2007 to 2008

1 For the Chicago O’Hare weather station http://cdo.ncdc.noaa.gov/cgi-bin/climatenormals/climatenormals.pl

Natural gas: Increased consumption

1) Weather: 2007 winter was warmer than 2008, based on number of heating degree days (HDD)

• 2007: 6,022 HDD
• 2008: 6,678 HDD
• 30 year average: 6,498 HDD.1

2) Economy

Example: How to calculate heating degree days January 1, 2008: average temperature of 16°F Base temperature of a building: 65°F Number of heating degree days: 65 – 16 = 49

Slide 20

What’s Next

1) Strategies to reduce energy consumption

• Provide details on energy conservation measures; how they work;

financial/political feasibility

• Categorized by building sector; County corridor (Urban

Renaissance; Critical Growth; or Rural)

• Examine potential for energy savings countywide at varying

implementation levels; and at individual household/business level

2) Recommendations

• For implementation and moving forward
• Categorized by municipalities; county; utilities; joint action

Slide 21

What’s Next

3) Set of 2040 Energy Forecasts

• Business As Usual
• Aggressive

(aggressive action towards increasing energy efficiency)

• Moderate

(moderate action towards increasing energy efficiency)

• Limited

(limited action towards increasing energy efficiency)

Will be based

• n a mix of

strategies defined in the plan
