Goals Create:•useful visualizations•for embedding on the HEEP website•that are easy for HEEP to maintain

Technology:•Google Visualizations•Google Docs (spreadsheets)

(3)

The Visualizations Don’t waste your money!•Rebate incentivizer

Negawatt Calculator•HEEP rebates and avoided energy cost

HCEI goal trends•Progress toward 2030 targets

But first, a few ideas that didn’t make the cut...

Negawatt Visualizer Negawatt: 1 watt of avoided electrical use.

Visualizer calculates:•Total negawatts generated by rebates.•Total avoided energy cost.•Total rebate cost.•Amortized negawatts/rebate dollar.

HCEI trends Goals of HCEI (we think):•Reduce total generation from 2007 levels by 30%.-From 33,478 GWh to 23,434 GWh.

•In 2030, 40% of 2007’s total generation should be from renewables. -33,478 GWh * .40 = 13,391 GWh

•So, fossil fuel should account for 23,434 - 13,391 = 10,043.

Don’t waste money Shows anticipated savings from installing Energy Star appliances.

For a given class of appliance, shows:•Rebate (fixed)•Yearly savings (varies by class).
