Purpose The purpose of this paper is to examine the impact of fossil fuel prices – crude oil, natural gas and coal – on different electricity prices in Mexico. The use of alternative variables for electricity price helps to increase the robustness of the analysis in comparison to previous empirical studies. Design/methodology/approach The authors use an unrestricted vector autoregressive model and the sample covers the period January 2006 to January 2016. Findings Empirical findings suggest that crude oil, natural gas and coal prices have a significant positive impact on electricity prices – domestic electricity rates – in Mexico in the short run. Furthermore, crude oil and natural gas prices have also a significant positive impact on electricity prices – commercial and industrial electricity rates. Originality/value Two are the main contributions. First, this paper explores the nexus among crude oil, natural gas, coal and electricity prices in Mexico, while previous studies focus on the US, UK and some European economies. Second, instead of using one electricity price as a reference of national or domestic electricity sector, the analysis considers alternative Mexican electricity prices.

Power is one of the key requirements for the development of economies and upgrading of standards of living of developing countries. Countries such as Bangladesh depend largely on fossil fuels such as diesel fuel and natural gas to produce the main proportion of their electricity. However, this country’s combination of limited natural gas reserves high fuel prices and escalating costs of transmission and distribution lines has greatly increased the unit cost of electricity generation and it is becoming difficult for customers to pay for electricity. On the other hand, burning fuel causes environmental pollution that leads to global warming which is ultimately responsible for climate change and its devastating consequences. In this study, we have recommended a stand-alone system for the traditional consumption of domestic electric use at residential units in Bangladesh. We have shown a comparison of using the stand-alone photovoltaic (PV) system with the traditional grid connection. Although the initial set-up cost is high, it becomes profitable as people are supplied with electricity, which is being generated from PV as a result minimizing the energy cost from the grid, and in addition, they can later make savings from this system. This paper, therefore, aims at determining the optimum size of the rooftop solar home system that will fulfil all the criteria for powering up electrical appliances at an affordable price. Comparative analysis of both energy systems based on the cost calculation has been performed by means of the Hybrid Optimization of Multiple Energy Renewables (HOMER) software. The validity of this proposal and its usefulness is also analysed.

The Cost

This paper assesses performances and economic viability of CO2 removal by chemical absorption from the flue gases of natural gas-fired Combined Cycles, more specifically for two configurations: one where CO2 is removed ahead of the stack without modifying the power cycle; the other where part of the flue gases is recirculated to the gas turbine, thereby reducing the flow to be treated by chemical absorption. In both cases sequestered CO2 is made available at conditions suitable to storage into deep oceanic waters. Performances and cost of electricity are evaluated for systems based on large, heavy-duty turbines representative of state of the art “FA” technology. Carbon sequestration reduces net plant efficiency and power output by about 10% and increases the cost of electricity from 36 to about 50 mills/kWh. Flue gas recirculation warrants slightly higher efficiencies and lower costs. CO2 removal is eventually compared with other strategies for the reduction of CO2 emissions, like switching existing coal-fired steam plants to natural gas or replacing existing steam plants with conventional CCs. At current fuel prices the latter appears the option of choice, with a cost of about 25 $ per tonn of avoided CO2 emission.

Multiple Bubbles

In the recent past, the world in general and Pakistan in particular faced a drastic fuel price change, affecting the economic productivity of the country. This has drawn the attention of empirical researchers to analyze the abrupt change in fuel prices. This study takes a lead and investigates for the first time, in the literature related to Pakistan, the presence of multiple fuel price bubbles, with the purpose of knowing if the price driver is due to demand or it is exuberant consumer behavior that prevails and contributes to a sudden boom in fuel price series. The empirical analysis is performed through a recently proposed state-of-the-art generalized sup ADF (GSADF) approach on six commonly used fuel price series, namely, LDO (light diesel oil), HSD (high-speed diesel), petrol, natural gas, kerosene, and MS (motor spirit). The bubble analysis for each of the six fuel price series is based on monthly data from July 2005 to August 2020. The findings provide evidence of the existence of multiple bubbles in all series considered. Specifically, four bubbles are detected in each of the kerosene and natural gas price series, whereas three bubbles are noted in each of the HSD, LDO, petrol and MS price series. The maximum duration of occurrence of bubbles is of 12 months for kerosene. The date-stamping of the bubbles shows that the financial crisis of 2008 contributed to the emergence of bubbles that pushed oil prices upward and caused a depreciation in the national currency.

Natural Gas Prices

Since 2007, US coal-fired electricity generation has declined by a stunning 25 percent. Detailed daily unit-level data is used to examine the joint impact of natural gas prices and wind generation on coal-fired generation and emissions, with a focus on the interaction between gas prices and wind. This interaction is found to be significant. Marginal responses of coal-fired generation to natural gas prices (wind) in 2013 were larger, sometimes much larger, than the counterfactual with 2008 wind generation (gas prices). Additionally, these factors jointly account for the vast majority of the observed decline in generation and emissions. (JEL L94, L95, Q35, Q38, Q42, Q53)

Recent advances in extraction have increased the supply of natural gas and increased the relative price difference between it and alternative fuels.  However, natural gas is not available in many rural areas forcing poultry producers unable to access natural gas to use more expensive fuels. This paper determines the least cost appliance system and fuel source for heating a broiler chicken barn in Ontario, Canada. The empirical model estimates the amount of heat required for poultry production, selects appropriate heating appliances and fuel types, and calculates the final present value of costs over a 20-year period. Appliances examined include box heaters, radiant tube heaters and biomass boilers; fuels examined include natural gas, propane, heating oil and biomass.  Natural gas is the least cost fuel for both box heaters and radiant tube heaters assuming there is an existing connection to a gas pipeline.  However, natural gas heating systems become the most expensive approach if the poultry operator has to pay for a pipeline connection to the gas source. With no direct connection for natural gas, biomass boilers are the most cost efficient heating system, followed closely by radiant tube heaters fuelled by propane. Heating oil is the most expensive fuel examined and its costs are nearly double that for comparable box heaters and radiant tube heaters using propane.

As fossil fuel prices rise and emission allowances are implemented, solar augmented steam cycles might be an attractive option for energy companies. The system utilizes steam generated by a solar field in a conventional natural gas or coal-powered steam cycle, offsetting some of the fuel required to generate power. Many energy companies are interested in adding solar power to their generating mix, but today most solar applications are not cost-competitive with other power generating options. Solar augmentation potentially is the lowest cost option for adding solar power to the generation fleet. The highest intensity solar energy typically is within a few hours of peak summer loads, making it a particularly attractive renewable option.
