The world's transition to a fully sustainable energy system could be possible by 2050, meeting the 1.5 degrees Celsius Paris global warming target.
FREMONT, CA: By utilising renewable energy sources to meet the rising energy demands, nations all around the world are moving toward a low-carbon future. The urgent need to gradually transition to renewable energy sources is needed to address this. Businesses can also play a significant part in energy self-sufficiency by implementing solar power for their diverse energy needs. Additionally, transitioning to a steady and consistent source of energy makes sense because the fluctuating cost of power is one of a large company's highest overhead costs. However, making the switch to solar requires thoughtful planning and calculated action. Rooftop installations have greater upfront costs, but as the electricity can be partially or entirely used on-site, the value is correlated with the applicable industrial or residential retail pricing. Rooftop PV also improves supply and demand's geographic fit, a point that will become more crucial as we gradually electrify the heating, cooling, and transportation sectors. According to several studies, even in the most ambitious cases, roof space is not an issue.
Many economists claimed that assistance for PV deployment was not warranted earlier in the technology's development stage since PV's unit abatement cost was higher than that of alternative mitigation approaches. PV costs have decreased over the past few decades as a result of public assistance for both R&D and adoption (see Kavlak et al. 2018, or David Roberts' good review). PV is on track to overtake other electricity generation technologies as the least expensive in many places. This occurred with PV modules, but the scenario for distributed PV might be similar.
Due to a lack of economies of scale, greater transaction costs, and other market impediments to small-scale dissemination, its present cost is significantly higher than that of centralised PV. Rooftop photovoltaic systems are currently often erected randomly. If the PV system is installed at the time of roof renovation or construction, cost savings might be realised. Additionally, the distributed market might benefit from the lower cost of centralised PV due to the standardisation of building-integrated PV and the creation of new business models for shared power self-consumption.
The utilities rejected the solar industry's suggestion to gradually implement the new export payments, calling it a desire to maintain the inequality generated by the current net energy metering programme. Promoting distributed PV raises the total amount of investment made for the energy transition since it attracts capital from sectors that otherwise would not invest in clean energy. Because of this, encouraging distributed PV is not a zero-sum strategy because it increases overall decarbonization investment, and all efforts will be required to reach the climate targets. Large-scale PV may also be incompatible with other policy goals like biodiversity protection or even alternative methods of reducing greenhouse gas emissions like replanting, even when there is adequate land. Focusing solely on the least expensive solution might not be sufficient to alleviate environmental degradation at the required pace and scale given the enormous challenge of lowering emissions in line with the Paris targets.
The more aggressive rate reform proponents proposed that existing customers be switched to the new pricing eight years after their system was installed. They reasoned that this would give them plenty of time to pay back their system and would still allow them to continue saving money on their bills, although at the lower new rate.
