Our mobility will be adversely hampered , not to mention the reliability of global communication on energy . As we embrace the digital economy , data centres , which form a critical part of digitalisation , cannot effectively function without enough energy .

At the same , we also know that the wrong choice of energy can lead to deleterious consequences for our climate . Scientists have produced damning evidence that the burning of fossil energy is the single largest cause of the rising greenhouse gas levels in the atmosphere .

But , the suggestion to phase out fossil fuels has faced fierce resistance . The reason is quite apparent . Fossil fuel is the most abundant and is the cheapest . It is a dilemma for the world .

“ CAN THE WORLD LIVE WITHOUT FOSSIL FUEL ?”

At MAPAN , we recently convened a meeting to share views on the topic “ Can the World Live Without Fossil Fuel ?”. Living without fossil fuels is a complex challenge , but many say it is possible with significant changes in technology , infrastructure , and policy .

We need to build renewable energy sources . Some view solar and wind power as the most promising alternatives to fossil fuels . Advances in technology and reductions in cost have made solar and wind power more viable . Not everyone agrees , though .

renewable energy source , though its expansion is limited by geographical and environmental considerations . Geothermal energy provides a constant and reliable source of energy in certain regions .

Biomass as organic materials can be used to produce energy , though this has its own environmental and land-use challenges . Clearly , all the mentioned renewables have their limits .

Efficient energy storage and grid management are needed when transitioning to renewables . The sun does not shine all the time , while the wind speed is never consistent .

Advances in battery storage are crucial for managing the intermittent nature of solar and wind power . At the same time , we need smart grids to manage supply and demand better , thus enhancing the efficiency and reliability of renewable energy .

There are also policy and economic factors to consider . Subsidies for renewable energy , carbon pricing , and regulations can drive the transition away from fossil fuels . Not to mention , significant investment in research , development , and infrastructure is necessary .

Moving away from fossil fuels can impact economies dependent on oil , coal , and natural gas . Malaysia is a good example . A big chunk of our revenue comes from oil and gas . Transition plans are needed . This explains why we have adopted NETR .

NUCLEAR POWER

Other options are also under the world ’ s radar . Nuclear power is one . While controversial , nuclear energy is a low-carbon alternative to fossil fuels .

There have been reported developments in nuclear technology as well .

The world is in an advanced stage of a commercial trial with nuclear fusion technology , which many claim is much safer . The reaction simulates the sun . Then , we have hydrogen fuel to consider .

Hydrogen can be used as a clean fuel if produced using renewable energy . Attempts are underway to improve the viability of hydrogen . The fossil fuel group has come up with a carbon capture and storage ( CCS ) approach to reduce emissions .

Admittedly , this technology can help reduce emissions from remaining fossil fuel use during the transition period . However , some also question whether it is realistic .

Many see lifestyle and cultural changes as key . Improved energy efficiency in buildings , transportation , and industry can reduce overall energy demand . Then , there are the needed behavioural changes .

Shifts in consumption patterns and lifestyles can contribute to reducing fossil fuel dependence . Many agree on the need for effective global coordination . This is the most challenging .

There is no denying that addressing climate change and transitioning to renewable energy requires global collaboration and shared commitments . The transition away from fossil fuels is challenging but achievable with concerted efforts across multiple sectors and at all levels of society .

Notwithstanding , some sceptics remain doubtful that there will ever be a viable replacement for fossil fuel . The best bet is still nuclear ! – @ green
