We consider the problem of optimally determining an investment portfolio for an energy company owning a network of gas pipelines, and in charge of purchasing, selling and distributing gas. We propose a two stage stochastic investment model which hedges risk by means of Conditional Value at Risk constraints. The model, solved by a decomposition method, is assessed on a real-life case, of a Brazi...

This study investigates the dynamic impact of green energy investment and consumption on carbon emissions in China from 1995 to 2020. It employed Bootstrap Autoregressive Distributed Lag method examine short long-run relationship. The findings indicate that renewable decrease emissions, whereas non-renewable economic growth increase shorter longer periods. long-term reduction may imply transiti...
