Alternative Energy Sources That Can Make A Difference
Mike and Mark launch the second part of the podcast talking about the potential of renewable energy and electrification to significantly reduce electricity costs for more remote locations. As Mark notes, Hawaii, for example, could see a big drop in prices due to increased reliance on renewable energy and less reliance on fossil fuels that must be shipped to a distant state. The two experts also explore how renewable energy produces grid reliability and countless other benefits and, as Mark explains, will be cheaper in the future than our current energy sources, even with more conservative projections.
Mike and Mark then move on to talk about pumped hydropower and storage as well as other energy sources including nuclear. They conclude that nuclear is not something to include in future plans because current cost assumptions are underestimated and the time it takes to build a plant is not commensurate with the need for a rapid transition to cleaner energy sources.
Mike and Mark explore their thoughts on what has changed in terms of the energy landscape over the past decade. From a global engineering and policy perspective, Mark notes the falling cost of renewables, the rise and development of electric cars, and battery storage breakthroughs. He is particularly excited to see the enthusiasm surrounding the movement to transition to 100% renewable energy globally.
The two wrapped up the podcast by briefly sharing their thoughts on the Green New Deal and the nonpartisan nature of the transition to renewable energy. As Mark notes, even conservative politicians are embracing renewable energy because it has been shown to be the most cost-effective option.

Winter is a Cutler Scholar and an undergraduate student at Ohio University’s Honors Tutorial College double majoring in Environmental Studies and Journalism, with a minor in French. Her academic interests include environmental communication, technology and social innovation, particularly as they relate to international climate change mitigation and adaptation. Although Winter attends school in her hometown of Athens, Ohio, she takes advantage of her breaks to explore the outside world. She spent her most recent sabbatical conducting self-directed research on climate change and environmental justice in Southeast Asia. This year, he will complete his dual thesis on climate change communication and a complementary documentary series. Excited to contribute and work with the team as Winter Summer Editorial Intern.

I was recently able to interview Celina Mikolajczak, …before the global pandemic, the world’s energy supply sources followed long-term trends, with new fuels increasing their share and old fuels losing ground. Below, you can see the usage history from the year 1990 to 2018.
Leveling Up Humanity: The Energy Sources Of The (far) Future
Over the past four decades, oil has been the world’s leading source of primary energy consumption, and is expected to remain so during the forecast timeframe. Liquids (mainly oil and other petroleum products) are expected to continue to provide the largest share of world energy consumption during the forecast period.
In the transportation sector, in particular, liquid fuels continue to provide the majority of energy. Although advances in non-liquid-based transportation technologies are expected, they are not enough to offset the growing demand for transportation services worldwide. As a result, oil is projected to maintain its dominance in the global energy mix and reach 30% of total primary energy consumption in 2040.
Worldwide natural gas consumption is projected to increase from 120 trillion cubic feet (Tcf) in 2012 to 203 Tcf in 2040. By energy source, natural gas accounts for the largest increase in world primary energy consumption. Abundant natural gas resources and strong production from shale resources contribute to a strong competitive position of natural gas among other resources. Natural gas is the main fuel in electric power sector and industrial sector.
It is seen as a desirable alternative to electric power given its relative efficiency and environmental advantages compared to other fossil energy sources.
Energy Storage Of The Future
Natural gas burns cleaner than coal or oil, making it a more attractive choice for countries looking to reduce greenhouse gas emissions.
Coal is the world’s slowest growing energy source, increasing by an average of 0.6%/year from 153 quadrillion BTU in 2012 to 180 quadrillion BTU in 2040. Throughout the projection, the top three coal-consuming countries were China, the United States, and India, which accounted for more than 70% of world coal consumption.
The use of coal in developing countries will continue to increase, but in developed or industrialized countries it will not increase but may decrease slightly.
Global coal production is projected to increase from 9 billion short tons in 2012 to 10 billion short tons in 2040. Most of the projected growth in world coal production is in India, China and Australia.

Coal is an important fuel for the world’s electricity markets and is expected to continue to dominate energy markets in developing Asia.
According to the International Energy Outlook 2019, the strongest growth in electricity production is expected to occur in developing, non-OECD nations. Non-OECD electricity production increases by an average of 2.5%/year from 2012 to 2040, as rising living standards increase demand for home appliances and electronic devices, as well as commercial services including hospitals, schools, office buildings and shopping malls. In OECD countries, where infrastructure is more mature and population growth is relatively slow or declining, electric power generation increases by an average of 1.2%/year from 2012 to 2040.
As can be seen from the figures, the role of renewables is expected to change drastically in the coming years. What a transition!
According to the International Energy Outlook estimates by the US Department of Energy (US DOE), there is still considerable uncertainty about the future of nuclear power, and a number of issues could slow the development of new nuclear power plants. Issues related to plant safety, disposal of radioactive waste, and proliferation of nuclear material raise public concerns in many countries and hinder plans for new installations. Although the long-term effects of the disaster at Japan’s Fukushima Daiichi nuclear power plant for world nuclear power development are unknown, Germany, Switzerland and Italy have already announced plans to phase out or cancel all their current and future reactors. In contrast, developing Asia is poised for a strong expansion of nuclear production. Much of the increase has come from China’s addition of 139 gigawatts (GW) of nuclear capacity from 2012 to 2040.
Transitioning The World To 100% Renewable Energy — Part 2
In a nuclear plant, nuclear fission (splitting the nucleus of an atom into many new atoms) produces heat within the uranium fuel. As a result of the split, heat energy is released and the steam spins a turbine generator to produce electricity.
The world consumption of renewable energy resources is projected to grow significantly over the next 25 years. Much of the projected growth in renewable generation is expected to result from the completion of solar installations around the world. A dramatic drop in the cost of solar panels makes this source one of the cheapest forms of electric power generation by 2020. In 2020, 90% of all new electric power generation installations worldwide were renewable.
In hydroelectricity, mechanical energy from water pulled downward by gravity is converted into electricity.
