How Will Renewable Energy Help Climate Change

Climate change is an existential threat that needs immediate attention and action. The world is warming up, and the consequences are becoming increasingly evident. Extreme weather events are becoming more frequent and severe, causing billions of dollars in damages.

One of the primary drivers of climate change is the burning of fossil fuels for energy production. This emits large amounts of greenhouse gases into the atmosphere, leading to global warming. Transitioning the fossil fuel industry to renewable energy sources, such as biofuels, wind, solar, and hydropower, can play a pivotal role in mitigating climate change’s adverse effects and ensuring a sustainable future for our planet.

Introduction

Our journey towards understanding climate change and its connection with renewable energy begins with understanding what climate change is and how it is influenced by human activities. We then delve into the various types of renewable clean energy technologies, their implications for climate change, and how their adoption could shape our future.

Understanding Climate Change

Climate change refers to long-term shifts in temperatures and weather patterns. It is primarily a consequence of human activities. As we burn fossil fuels like coal, oil, and natural gas for energy, they release carbon dioxide and other greenhouse gases into the atmosphere. These gases trap heat from the sun, causing the Earth’s average temperature to rise, a phenomenon known as global warming.

This increase in the Earth’s average temperature leads to changes in climate patterns, resulting in events such as more intense and frequent storms, severe droughts, heatwaves, and rising sea levels.

Renewable energy sources, such as wind power and solar, produced approximately 28.8% of global electricity in 2020, reducing over 2 billion metric tons of carbon dioxide (CO2) emissions, as reported by the International Energy Agency (IEA).

The Role Of Energy Production In Climate Change

The energy sector is a significant contributor to global greenhouse gas emissions, primarily through the burning of fossil fuels. These sources of energy release vast amounts of carbon dioxide when burned, contributing to the increasing concentration of greenhouse gases in our atmosphere. This trend makes the energy sector a critical target for interventions aimed at reducing greenhouse gas emissions.

Renewable energy sources, like wind, solar, and hydroelectric power, offer a viable alternative. They generate electricity without releasing harmful gases, making them vital in the fight against climate change. In the past decade, advancements in technology have made these sources nuclear power even more efficient and affordable, encouraging their adoption worldwide.

As of 2020, the world’s renewable energy capacity surpassed 2,799 gigawatts (GW), as stated by the International Renewable Energy Agency (IRENA). This substantial capacity contributes significantly to reducing fossil fuel reliance.

Renewable Energy: An Overview

Renewable energy comes from natural sources that replenish themselves over short periods of time. They include sunlight, wind, rain, tides, waves, and geothermal heat. Each type biomass energy presents unique advantages and challenges, but all contribute to a cleaner, healthier environment.

Wind energy harnesses the power of the wind to generate electricity. Wind turbines, which may be onshore or offshore, convert the wind’s kinetic energy into mechanical energy, which is then converted into electricity. Solar energy, on the other hand, uses solar panels to capture sunlight and convert it into electricity. Hydroelectric power uses the energy of falling or flowing water to generate electricity, typically through dams. Geothermal solar thermal energy also taps into the Earth’s internal heat to produce electricity and heat for buildings.

Bioenergy comes from organic materials like plants and waste. Biomass, such as wood, crops, and animal waste, can be burned directly for heating or power generation, or converted into biofuels for transportation. However, it’s worth noting that not all bioenergy is carbon-neutral, and some biofuels can cause environmental problems of their own.

According to the IEA, solar power capacity grew by 127 GW globally in 2020. This massive expansion in solar energy is instrumental in the transition to cleaner energy sources.

The Impact Of Renewable Energy On Climate Change

Renewable energy technologies hold the promise of mitigating climate change by reducing our dependence on burning fossil fuels and fuel-based energy sources. Here are some ways renewable energy helps combat climate change:

1. Reducing Carbon Emissions

Renewable energy sources produce little to no greenhouse gas emissions during operation, significantly reducing the overall carbon footprint of energy production. For example, the use of biofuels in transportation can result in lower carbon emissions compared to conventional fuels. Corn ethanol, for instance, averages just under 40 percent lower carbon emissions than using only gasoline.

Wind energy capacity reached approximately 731 GW in 2020, according to the Global Wind Energy Council (GWEC). Wind power sector’s rapid growth plays a crucial role in reducing greenhouse gas emissions.

2. Conserving Water

Traditional power plants require a lot of water for cooling and process requirements. On the other hand, most sources of renewable energy, like offshore wind turbines and solar photovoltaics, require no water to generate electricity. This advantage can be particularly important in arid regions or during times of water scarcity.

3. Enhancing Energy Security

Renewable energy also enhances energy security by reducing dependence on imported fuels. This diversification of energy sources increases resilience to fuel price volatility and supply disruptions. Moreover, renewable energy resources are abundant and widely distributed geographically, further contributing to energy security.

Hydropower accounted for 16% of the world’s total electricity generation in 2020, as reported by the IEA. This longstanding renewable source continues to provide a significant share of clean, electricity generation.

Transitioning To Renewable Energy

The Information Technology and Innovation Foundation has also developed several recommendations to bolster the implementation of renewable energies like biofuels. These recommendations include increasing investments in bioenergy and biomanufacturing research and development by 150 percent in the next five years, supporting biofuels development for aviation, shipping, and other hard-to-electrify transportation sectors, and expanding research into gene-editing tools that can improve biomass processing.

Challenges In Adopting Renewable Energy

Despite the numerous benefits, there are still several challenges that need to be addressed to fully transition to all renewable sources of energy.

1. Infrastructure Changes

Transitioning to renewable energy on a large scale requires significant changes to existing energy infrastructure. This includes building new power plants, developing improved energy storage solutions, and upgrading the electricity grid to handle a higher proportion of renewable energy. These changes require substantial investment and careful planning.

The IEA estimates that by 2030, renewables will provide 30% of the world’s electricity, significantly reducing CO2 emissions from generating electricity, and helping limit global temperature rise.

2. Economic Constraints

While the costs of most renewable energy sources and technologies have been decreasing rapidly, initial installation costs can still be high, making it challenging for some to adopt these technologies. Additionally, the intermittent nature of some renewable energy sources, like wind and solar, means that they can’t always provide power when needed, leading to additional costs for storage or backup power.

3. Social And Cultural Factors

Social and cultural factors can also pose challenges to the adoption of renewable energy. For instance, some people object to the visual impact of wind turbines on landscapes. Similarly, concerns about air pollution and the noise created by wind turbines have been raised. There are also concerns about the impact of renewable energy projects on local communities and ecosystems, such as the effect of large dams on river ecosystems and surrounding communities.
