Renewable energy has become an increasingly important topic in recent years, as the world looks for ways to reduce its reliance on fossil fuels and combat climate change. One of the best sources of renewable energy is solar power, which has seen a rapid emergence and growth in recent years. In this blog post, we will explore the emergence of renewable energy with a focus on solar power.

The Emergence of Renewable Energy

The emergence of renewable energy can be traced back to the 1970s, when the oil crisis led to a search for alternative sources of energy. The focus at that time was primarily on wind and hydroelectric power. However, it wasn’t until the 1990s that solar power started to gain traction as a viable source of renewable energy.

One of the key factors driving the emergence of renewable energy has been the increasing awareness of the negative impacts of climate change. As more and more people become aware of the environmental and social impacts of burning fossil fuels, there has been a growing demand for cleaner sources of energy. Additionally, advances in technology have made renewable energy more efficient and cost-effective, further driving its emergence. 

An example of how cheap renewable energy has become can be seen in the Australian National Energy Market (NEM) data, which is publicly available to view via the following link: https://opennem.org.au/energy/nem/?range=7d&interval=30m

Opennem.org.au is a website that shows energy flows in the NEM including Consumption data and Generation data across all sources of energy. Over the last 7 days, 31 March 2023 – 7 April 2023, renewable energy sources accounted for 33.6% of the energy mix generating 1,281 GWh of energy just from renewables. The balance is produced through fossil fuels including coal and gas facilities. 

Looking at each energy source category and the average cost per MWh:

• Solar was $67.35
• Wind was $115.85
• Hydro was $141.29
• Gas was $146.68
• Coal was $119.45

The cheapest energy source was from solar power generators which is a combination of rooftop solar and utility scale solar power plants. You can see on the graph showing the price $/MWh over the course of the week being reviewed, is the daytime value of energy during the daytime is significantly lower than the evening and nighttime energy. 

The stats show us the lowest cost of energy on the NEM during the week was on the 2nd of April at 12 PM midday with a negative price value of -$15.58 p/MWh when solar contributed to 52.4% of the NEM energy mix. Conversely the highest cost of energy was on the 5th of April at 6pm at value of $706.00 p/MWh when coal was providing the 60.7% of the energy mix, gas 16.2% and solar was only contributing to 1.4% of the energy mix in the NEM. 

The final point on this particular set of data for the week or 7 days from the 31st March 2023 – 7th April 2023, is the demand for energy. The minimum demand of 6,493MWh was on March 31st at 12:30am. The maximum demand of 26,610MWh was on the 5th of April at 1:00pm and renewable energy made up 57% of the energy mix and the average cost of energy across all sources was $67.45 p/MWh. 

What this highlights is the low cost of renewable energy in 2023 as well as the relevance of solar generation in the renewable energy mix to help supply energy during times of peak energy demand.

The Growth of Solar Power

Solar power has seen rapid growth in recent years, as improvements in technology have made it more efficient and cost-effective. The cost of solar panels has decreased significantly, making it more accessible to a wider range of people and businesses. In fact, solar power has become the cheapest source of energy in many parts of the world, making it an attractive option for both developed and developing countries.

The growth of solar power has also been driven by government incentives and policies. Many governments around the world have implemented policies to encourage the adoption of renewable energy, such as tax credits, feed-in tariffs, and renewable portfolio standards. These policies have helped to spur investment in solar power and make it more competitive with traditional sources of energy.

Benefits of Solar Power

There are many benefits to using solar power as a source of renewable energy. Perhaps the most significant benefit is its potential to reduce greenhouse gas emissions and combat climate change. Solar power is a clean, renewable source of energy that does not produce any harmful emissions. Additionally, it is abundant across all areas of the globe, making solar power a promising source of energy for the future.

Solar power also has the potential to create jobs and boost economic growth. As the solar industry grows, it creates new jobs in manufacturing, installation, and maintenance. Additionally, solar power can help to reduce energy costs for businesses and households, freeing up money for other expenses. There are financial products that enable home owners and business owners alike to spend zero dollars upfront and pay for the solar installation through energy savings. 

Conclusion

The emergence of renewable energy, and solar power in particular, represents a promising step towards a more sustainable future. As technology continues to improve and government policies continue to support the adoption of renewable energy, we can expect to see continued growth in the solar industry. 

This growth has the potential to not only reduce greenhouse gas emissions and combat climate change, but also create jobs and boost economic growth. I for one will continue to help drive this change from the front to help ensure our children have a brighter future ahead. 

Climate change is one of the most pressing issues facing the world today. It is caused by a variety of factors, both natural and human-induced. The primary cause of climate change is the increase in greenhouse gases in the atmosphere, mainly carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) and chlorofluorocarbons CFC’s). These gases trap heat from the sun, leading to a warming of the planet’s surface.

Human activities are the main contributors to the increase in greenhouse gas concentrations in the atmosphere. These activities include burning fossil fuels such as coal, oil, and gas, deforestation, agriculture, and industrial processes. The burning of fossil fuels releases large amounts of CO2 into the atmosphere. Deforestation and agriculture also contribute to climate change by reducing the number of trees that can absorb CO2 and by releasing CH4 and N2O from the soil.

Another factor that contributes to climate change is the increase in the Earth’s population. As the global population grows, so does the demand for energy, food, and resources. This leads to increased emissions of greenhouse gases and deforestation to make way for agriculture and housing.

There are several solutions to climate change that can be implemented to reduce greenhouse gas emissions and slow the rate of warming. One of the most effective solutions is to reduce our reliance on fossil fuels and transition to renewable energy sources such as solar, wind, and hydropower. This can be achieved through policies that promote the use of renewable energy, such as tax incentives, subsidies, and regulations that require the use of renewable energy sources.

Another solution is to increase energy efficiency and conservation. This can be achieved through measures such as improving the insulation of buildings, promoting the use of energy-efficient appliances and equipment, and encouraging people to use public transportation, walk, or cycle instead of driving.

Reducing deforestation and promoting reforestation is another solution to climate change. Trees absorb CO2 from the atmosphere and provide habitats for many species, helping to maintain biodiversity. Governments can implement policies to protect forests and encourage reforestation, and individuals can support these efforts by choosing to buy products from companies that use sustainable forestry practices.

Finally, individuals can reduce their carbon footprint by making lifestyle changes, such as reducing meat consumption, using energy-efficient appliances, driving less, and recycling.

In conclusion, climate change is a complex issue caused by a range of natural and human-induced factors. To address this problem, we need to implement a range of solutions, including reducing our reliance on fossil fuels, increasing energy efficiency and conservation, reducing deforestation, promoting reforestation, and making lifestyle changes. By taking action now, we can help to slow the rate of warming and ensure a sustainable future for our planet.

Another factor that has contributed to Australia’s leadership in rooftop solar is the country’s high electricity prices, which have led many homeowners and businesses to look for alternative sources of energy. Rooftop solar provides a cost-effective solution to high electricity bills, and as a result, many Australians have embraced this technology.

Furthermore, the Australian solar industry has matured over the years, with the development of high-quality, efficient solar panels and other related technologies. This has made rooftop solar more affordable and accessible to a wider range of consumers.

Finally, Australia has a strong culture of environmental awareness and sustainability, and many Australians are motivated to adopt rooftop solar for its environmental benefits as well as its economic benefits.

Overall, the combination of favourable climate conditions, government incentives, high electricity prices, technological advancements, and a strong environmental consciousness have all contributed to Australia’s position as a world leader in rooftop solar.
