Beneath Pakistan's mighty rivers lies an immense, pristine water resource estimated at around 500 million acre-feet (MAF). This resource not only has the potential to satisfy the needs of the rapidly growing population, but also to ensure food security through smart agriculture. By harnessing this resource, Pakistan could alleviate the burden of waterborne diseases by pumping and supplying it to cities and towns, while fostering smart agriculture in dry regions like Cholistan. This approach could not only alleviate hunger, but also correct trade imbalances without the need for constructing huge and costly dams. However, to effectively utilize its aquifers and secure long-term prosperity for its citizens, the country must first overhaul its energy landscape.
The energy landscape of Pakistan is at a critical juncture, where the balance between energy demand and supply, coupled with environmental concerns, has necessitated a paradigm shift towards sustainable solutions. Despite significant strides in energy generation capacity, the country grapples with challenges of reliability, affordability, and environmental sustainability. A holistic evaluation underscores the imperative to augment the share of solar energy in Pakistan's energy mix to ensure a sustainable future.
As per a NEPRA report of 2022, the country’s total installed energy generation capacity is 43,755 MW. Statistics show that energy sector heavily relies on conventional sources, primarily thermal and hydroelectric power, with a notable but underutilized potential in renewable energy. Thermal power, predominantly fuelled by gas and imported liquefied natural gas (RLNG), constitutes the largest share (59%), owing to its perceived affordability and accessibility. However, this reliance on fossil fuels poses multifaceted challenges, including environmental degradation, price volatility, and geopolitical vulnerabilities associated with imports.
The predominant reliance on fossil fuels exacerbates air pollution, contributing to respiratory illnesses and environmental degradation. The imperative to mitigate greenhouse gas emissions necessitates a transition towards cleaner, renewable energy alternatives.
Hydroelectric power, which makes up 25% of Pakistan’s power mix, despite its renewable nature, faces limitations such as seasonal variability and dependence on water resources, rendering it susceptible to climatic fluctuations. The share of nuclear energy (9%), though showing a promising trajectory, remains modest, while the contribution of renewable sources (7%), notably solar, lags far behind its potential.
Pakistan grapples with the adverse impacts of climate change, manifesting in erratic weather patterns, extreme temperatures, and natural disasters. The predominant reliance on fossil fuels exacerbates air pollution, contributing to respiratory illnesses and environmental degradation. The imperative to mitigate greenhouse gas emissions necessitates a transition towards cleaner, renewable energy alternatives.
The overreliance on imported fuels, coupled with geopolitical tensions, exposes Pakistan to supply disruptions and price fluctuations. Diversifying the energy mix with indigenous and renewable sources will enhance energy security, reducing vulnerabilities to external factors. The volatility of global oil and gas markets, coupled with the financial burden of energy subsidies, strains Pakistan's economy. Transitioning towards renewable energy, particularly solar, will not only mitigate price volatility but also stimulates economic growth through job creation, investment opportunities, and technological innovation.
The ageing power grid infrastructure, coupled with limited network capacity, poses a formidable bottleneck. The imperative to modernize and digitalize the grid infrastructure becomes paramount to seamlessly integrate renewables while ensuring grid stability.
Financing remains a daunting hurdle in Pakistan’s quest for energy transition. The updated nationally determined contribution (NDC) underscores the staggering costs associated with transitioning to renewable energy. With an estimated investment requirement of $101 billion by 2030 and an additional $65 billion by 2040, the onus falls on international cooperation and support to realize Pakistan’s ambitious targets.
Pakistan boasts abundant solar irradiance, offering an untapped reservoir of renewable energy. With vast swathes of land suitable for solar installations, harnessing solar power presents a viable and sustainable solution to meet the country's burgeoning energy demands.
Solar energy, emitting zero greenhouse gases, mitigates air pollution and preserves ecosystems. It reduces reliance on imported fuels, enhancing energy independence and national resilience. The sector offers economic opportunities in manufacturing, installation, maintenance, and R&D, fostering job creation, investment attraction, and economic growth. By nurturing a robust solar industry, Pakistan can stimulate a sustainable, inclusive economy.
Distributed solar power systems, such as rooftop solar panels and community solar projects, enhance the resilience of Pakistan's energy infrastructure. By decentralizing power generation and reducing dependence on centralized grids, solar energy mitigates the risk of disruptions and disasters, ensuring uninterrupted access to electricity for all.
Investing in solar energy generates job opportunities spanning engineering to sales, bolstered by local panel manufacturing reducing import reliance. Installation and maintenance services surge with solar adoption, benefiting SMEs.
The government must enact robust policy frameworks and financial incentives to promote solar energy adoption. Measures such as net metering, feed-in tariffs, tax incentives, and renewable energy quotas can incentivize investment in solar infrastructure and accelerate deployment.
Streamlining regulatory processes, enhancing access to financing and providing technical assistance can facilitate private sector investment in solar projects. Public-private partnerships and international cooperation can mobilize resources and expertise to catalyze solar energy development.
Investing in solar energy generates job opportunities spanning engineering to sales, bolstered by local panel manufacturing reducing import reliance. Installation and maintenance services surge with solar adoption, benefiting SMEs. R&D investment fosters tech advancement, enhancing affordability and efficiency, attracting domestic and foreign capital.
The stability and potential returns on investment in the solar industry attract capital, thereby stimulating economic growth not only within the sector, but also in related industries such as construction, finance, and real estate and agriculture. Furthermore, transitioning to solar energy enhances energy security by diversifying the energy mix and reducing reliance on imported fossil fuels, while also mitigating the environmental impacts associated with conventional energy sources.
The integration of solar energy into Pakistan's energy mix is not merely a choice but an imperative dictated by the urgency of climate change, energy security, and socioeconomic development. By harnessing its abundant solar resources, Pakistan can chart a path towards a sustainable and resilient future, characterized by clean energy, economic prosperity, and environmental stewardship. As stakeholders collaborate to overcome barriers and seize opportunities, the vision of a solar-powered Pakistan can transcend from aspiration to reality, illuminating the path towards a brighter tomorrow.
