Energy Prices and Turning Points: The Relationship between Income and Energy Use/Carbon Emissions

Amy K. Richmond and Robert K. Kaufmann

Year: 2006
Volume: Volume 27
Number: Number 4
DOI: 10.5547/ISSN0195-6574-EJ-Vol27-No4-7
View Abstract

Models used to test whether an environmental Kuznets curve (EKC) can be used to describe the relationship between GDP and energy use and/or carbon emissions may be biased by the omission of energy prices. Here we include real energy prices and fuel shares in models that describe energy use and carbon emissions. We test if these models show a turning point in OECD countries. Results indicate that including energy prices eliminates statistical support for a turning point and suggest that the relationship between income and both energy use and carbon emissions is represented most accurately by diminishing returns. These results imply that economic growth per se will not reduce energy use or emissions that cause global climate change.

Energy and Carbon Dynamics at Advanced Stages of Development: An Analysis of the U.S. States, 1960-1999

Joseph E. Aldy

Year: 2007
Volume: Volume 28
Number: Number 1
DOI: 10.5547/ISSN0195-6574-EJ-Vol28-No1-5
View Abstract

This paper explores the relationships among per capita income, energy consumption, and carbon dioxide (CO2) emissions by focusing on a set of economies at advanced stages of development, the U.S. states. Energy consumption and emissions grew 50�60 percent on average over the 1960�1999 period. The states� per capita energy consumption and emissions have grown on average 2 percent annually. The energy consumption income elasticity is positive but decreasing in income, although energy production takes an inverted-U shape, reflecting the electricity imports among high income states. The standard CO2 measure, corresponding to energy production, is characterized by an inverted-U environmental Kuznets curve. Adjusting emissions for interstate electricity trade yields an emissions-income relationship that peaks and plateaus. The carbon intensity of energy declines with income for total energy consumption and the industrial, residential, and commercial sectors.

Neoclassical Growth, Environment and Technological Change: The Environmental Kuznets Curve

Santiago J. Rubio, Jose L. Garcia and Jose L. Hueso

Year: 2009
Volume: Volume 30
Number: Special Issue #2
DOI: 10.5547/ISSN0195-6574-EJ-Vol30-NoSI2-7
View Abstract

This paper investigates socially optimal patterns of economic growth and environmental quality in a neoclassical growth model with endogenous technological progress. In the model, environmental quality has a positive effect not only on utility but also on production. Moreover, cleaner technologies can be used in the economy if a part of the output is used in environmentally oriented R&D. In this framework, if the initial level of capital is low, then the shadow price of a cleaner technology is low in relation to the cost of developing it, given by the marginal utility of consumption, and it is not worth investing in R&D. Thus, there will be a first stage of growth based only on the accumulation of capital with environmental quality decreasing until there is enough pollution to make investing in R&D profitable. After this turning point, if the new technologies are efficient enough, the economy can evolve along a balanced growth path with increasing environmental quality. The result is that the optimal investment pattern supports an environmental Kuznets curve.
