Energy efficiency Strategies stemming from KAYA
Optimising Energy in supply
CHP (Combined Heat and Power)
Minimising refinery losses, grid losses
Optimising Energy in demand
Sectors:
Buildings
industry
transport
Products: Eco-desigm
Energy services (combination of energy and technology)
Reducing demand for energy services
Sufficiency
De-growth
Possible energy efficiency benefits
What kinds of options can lie down to polictical decision making?
Top down: Options with largest saving potential
Bottom up: Remove hinderancees against savings in al fields
Barriers against Energy efficiency
Information barriers
Actor barriers: Investor-user, tenant-lessor dilemma
Financing barriers: High investment costs, risk surcharge at banks; transaction costs
Long project durations
Evaluation: Uncertainty about results -> Discounting
Ownership barriers: No person responsible for energy management, not part of thecore business, only low energy costs Explain tenant-lessor dilemma
Legal barriers (e.g. budget law)
Consumer behavior: four-wheel drive, wastefulness as a lifestyle
Rebound-Effect
As increased effiency is often associated with cost savings for consumer, this leads to more intensive use of product or/and purchase of additional products of the same type and/or consumes using freed-up funds for other energy-consuming products and services
Direct Rebound-Effect
Where increased efficiency leads to cost reduction and the tendency to consume more of that good or servic
Classic examples–the Jevons Paradox and the comfort factor
Indirect Rebond-Effect
Savings from energy efficiency enable more income to be spent on other products and services.
Macroeconomic Rebound-Effect
Increased efficiency improves economic productivity and drives growth, increasing consumption overall
Short and long term effects differ
