The natural gas consumption and economic development nexus: Fresh evidence from Indonesia
This study empirically examines the situation of country’s strategic planning to get achieved by utilizing the available resources and the association between capital and labor, natural-gas (NG) consumptions, and exports of the country. The current study is utilizing time-series data from the year 1980 to 2018. In order to confirm the cointegration Johansen Cointegration technique has been used while short-run and long-run coefficients are estimated by applying ARDL bound test. Results indicate that economic growth reduces while exports, and the consumption of capital and labor boost the use of natural gas (NG) in Indonesia. So, an affiliation between consuming natural gas consumption effects inversely by the economic growth of Indonesia.

Ensuring renewable energy consumption through innovation, R&D and Energy import in Indonesia: A time series analysis
This research sets the propositions as how factors like innovation, resource development and the imports of energy can help ensure renewable energy consumption in Indonesia for the period of 1995-2019. The independent variables for research are innovation, research and development, and energy import. The dependent variable is renewable energy consumption and the control variables are population growth and energy consumption. The analysis is obtained by using Augmented Dickey Fuller (ADF), unit root tests, co-integration tests and Autoregressive distributed time lag (ARDL) models to understand the effect in chosen time period. The results indicate that innovation, research and development have a significant impact on renewable energy consumption. However, energy import has not been significantly impacting in the short run. The research proposes significant implications for policy makers to make effective policies for R&D and for the companies to go for innovation as to use renewable energy.
