Is Renewable Worth It?

Is renewable worth it?

With climate change accelerating and fossil fuel supplies dwindling, the world is at an energy crossroads. There is an urgent need to transition to more sustainable energy sources that reduce greenhouse gas emissions. Renewable energy has emerged as a promising solution, offering clean alternatives like solar, wind, geothermal and more. But is renewable energy truly ready to replace fossil fuels? Can it realistically meet the world’s massive energy demands? There are pros and cons to consider. This article examines if renewable energy is worth the investment for our future.

What is Renewable Energy?

Renewable energy is derived from natural sources that can be replenished over time. Some of the most common renewable energy sources include solar, wind, hydro, geothermal, biomass, and ocean energy.

Solar energy is harnessed from the sun’s radiation and converted into electricity or heat using photovoltaic solar panels or solar thermal collectors. Solar energy does not produce any pollution or emissions.

Wind energy captures the wind’s kinetic energy using large wind turbines that generate electricity. Wind power is considered a clean and renewable source of energy.

Hydropower harnesses the energy from flowing water, such as waterfalls and dams, to produce electricity. Hydropower is one of the oldest and most widely used forms of renewable energy.

Geothermal energy utilizes heat from under the earth’s surface to provide heating and cooling or generate electricity. Geothermal energy is renewable and sustainable.

Biomass energy is derived from organic matter like plants, agricultural waste, and garbage. It can be used to produce transportation fuels, generate electricity, and provide heating.

Ocean energy harnesses power from waves, tides, currents, temperature differences, and salinity gradients in the ocean. Wave and tidal energy hold great potential as renewable electricity sources.

Pros of Renewable Energy

There are numerous benefits to transitioning our energy supply to renewable sources. Firstly, renewable energy produces little to no global warming emissions (1). Unlike fossil fuels, renewable sources like wind, solar, and hydropower don’t release greenhouse gases that contribute to climate change. In 2018 alone, renewable electricity generation avoided over 200 million metric tons of carbon pollution in the US (1). Widespread adoption of renewables is critical for reducing global carbon emissions and mitigating climate change.

Secondly, renewable energy promotes energy independence and security. The more we can produce energy domestically from renewable sources, the less reliant we become on imported fossil fuels (2). This makes our energy supply more secure and resilient. It also reduces our vulnerability to global oil and gas price fluctuations.

Finally, renewable energy can provide long-term cost savings compared to fossil fuels. While upfront costs are higher, studies show renewable electricity prices have fallen sharply in the last decade, making them cost competitive with conventional sources (3). And once installed, renewable energy has minimal ongoing fuel and operating costs compared to continually buying coal, oil, or gas. The fuel itself – wind, sun, water – is free. This provides more stable, predictable pricing over decades.

In summary, key pros of renewable energy are reduced emissions, energy independence, and long-term cost savings. Transitioning more of our energy mix to renewables brings tremendous environmental and economic benefits.




Cons of Renewable Energy

While renewable energy has many benefits, there are also some challenges and downsides to consider (Geothermal Energy Association).

One major downside is the high upfront costs associated with building and installing renewable energy systems. The initial capital costs for projects like solar panels or wind turbines can be quite high compared to fossil fuel plants (EnergySage). This can make financing and adoption more difficult, especially for individual homes and small businesses.

There are also intermittency challenges with some renewables like wind and solar. The energy production depends on factors like weather and daylight availability, which can make the electricity supply inconsistent. This requires integration with energy storage systems or backup power sources like natural gas (GreenMatch).

Connecting renewable energy projects to the wider electrical grid can also be an issue in some regions. New transmission infrastructure may be needed to transport electricity from large solar and wind farms to load centers. Grid upgrades can add time and costs to renewable energy projects.

Is Renewable Energy Affordable?

The costs of renewable energy have declined substantially in recent years, making it increasingly competitive with conventional fossil fuels like coal and natural gas. According to the International Renewable Energy Agency, between 2010 and 2019, the costs of solar energy decreased by 85%, and wind by 55%. Despite these declines, in most markets renewable energy still costs more than fossil fuels per kilowatt-hour without subsidies or incentives.

Government incentives and policies have played a major role in driving down costs and supporting the adoption of renewables. Tax credits, rebates, renewable portfolio standards and feed-in tariffs provide financial benefits to renewable energy producers and can help accelerate cost declines through economies of scale. However, renewables would likely not be cost competitive with conventional energy without these supports in many places.

While upfront costs of building renewable energy projects can be high, the “fuel” itself is free and operational costs are low. As technology continues to advance and scale expands, renewable energy is projected to achieve cost parity with fossil fuels globally within the next decade.

Case Studies

Several regions around the world have had great success with transitioning to renewable energy. Germany, for example, produced over 46% of its electricity from renewable sources in 2018 (Success Stories). The village of Feldheim now produces nearly all of its energy needs from local wind and solar power (25 percent local renewables success stories).

California is another renewable energy leader, with projects like the Desert Sunlight solar farm that powers 160,000 homes (Six stories show renewable energy underpins a climate-friendly future). Areas like Kern County are seeing economic revitalization from renewable investments.

Around the developing world, solar-powered water pumps are providing clean water access efficiently. Overall, these case studies showcase how renewable energy can power communities large and small while providing environmental and economic benefits.

Overcoming Challenges

The transition to renewable energy faces some key challenges that need to be addressed. One major challenge is the intermittent nature of sources like solar and wind. Solutions for intermittency include improving energy storage technology, having a diverse mix of complementary renewable sources, and implementing demand-side management techniques (

Another challenge is driving further adoption of renewables. Policies that can incentivize this transition include direct subsidies and tax credits, implementing carbon pricing systems, setting renewable energy targets, and updating grid infrastructure and electricity market rules to integrate more renewables ( Public investment into R&D and demonstration projects for next-generation renewable technologies can also accelerate cost reductions.

The Future of Renewable Energy

Most projections show renewable energy use growing substantially in the coming decades. According to the International Energy Agency (IEA), renewables are set to contribute 80% of new power generation capacity through 2030 based on current policy settings, with solar alone accounting for nearly 60% (source). The IEA predicts renewable electricity capacity will increase over 60% between 2020 and 2030 under stated policies.

The growth of renewable energy will play a key role in climate change mitigation efforts. The IEA projects that renewables will provide nearly 30% of global electricity supply by 2030, up from under 10% in 2019. Widespread adoption of renewable energy sources like solar, wind and hydropower will be essential to meet the greenhouse gas reductions targets outlined in the Paris Agreement and keep global warming below 2°C.

Consulting firm Deloitte forecasts renewable energy deployment in the United States will grow 17% in 2024 to 42 GW, accounting for nearly 80% of new electricity generation capacity (source). Looking further ahead, projections show renewables meeting around 50% of U.S. electricity demand by 2050.


In summary, renewable energy has both advantages and disadvantages. On the plus side, renewable sources produce little to no global warming emissions, do not require fuel, and help countries improve energy security by relying more on domestic resources. However, they currently tend to be more expensive than fossil fuels and provide power intermittently rather than 24/7. Despite the challenges, renewable energy will be critical for building a sustainable future. As technology improves and costs continue to fall, renewables have the potential to fully replace fossil fuels and dramatically reduce greenhouse gas emissions. With the right policies and investments, the world can transition to an affordable, reliable, clean energy system based largely on renewables like wind, solar, hydropower, biomass, and geothermal.
