2. ECO-JOWSGHP Efficiency Improved 15% (vs. conventional type) 35% (vs. model 20 years ago) CO2 Reduction 15% (vs. conventional type) 40% (vs. EHP) Subsidy (Yen/unit) 22 thousandsnil Price (Yen/unit) 400 thousands4.3 millions/42kw Sales Quantity (units accumulated) 340 thousands (LP Gas) 1.3 millions (LP Gas + City Gas) 2002~ By 2012, standardized 305 thousands (LP Gas) 707 thousands (LP Gas +City Gas) 1986~ Efficient Applications : Hot water and Air conditioning GHP 1 Heat pumps on the roof of the shopping center

3. ECO-WILLENE-FARM Efficiency Improved22% 30% CO2 Reduction 26%30~40% Subsidy (Yen/unit)124 thousands 1.4 millions Maximum Price (Yen/unit)800 thousands3 -3.5 millions Sales Quantity (units accumulated) 7.6 thousands (LP Gas) 89 thousands (LP Gas + City Gas) 2003~ One hundreds (LP Gas) 1.1 thousands (LP Gas + City Gas) May 2009~ Efficient Applications : CHP (Combined Heat & Power) 2

4. CHP + Solar Energy (Double Generation) Photovoltaic power generationFuel cell system 4kw type = 4,000kWh/year Running hour : 3hours/day 1kw type = 3,600kWh/year Running hour : 10hours/day + CO2 reduction : abt. 3.8mt/year Electricity from grid: 0.69kg-CO2/kWh LP Gas : 6kg-CO2/m3  ECO-WILL can be used instead of ENE-FARM  Excess electricity can be sold back to “grid”

5. Renewable Energy Challenges for utilizing biomass gas 1.On-site use : To use LP Gas as back-up. 2.By cylinder :Biomass DME for propane blending. Production of DME from Biomass Biomass DME mixing with LP Gas, supply by cylinder Gas supply Fermentation LP Gas mixing Power generation Output adjustment Concept: Utilization of Biomass Gas Biomass 4 On-site use
