British Gas-owner Centrica has seen its shares plummet over the past decade, but recent developments may indicate a potential turnaround. The company has been hit by increased competition, the shift towards renewables, and investor apathy towards traditional energy markets. However, recent energy price surges have allowed Centrica to fight back, and the collapse of smaller energy providers has given the company an opportunity to regain market share. Centrica has also made efforts to transition towards renewable energy, with a net-zero target of 2040 and significant investment in renewable infrastructure. However, concerns remain over the company's gas storage limitations and regulatory uncertainty.
