The States should consider constructing an electricity cable under the sea to France, according to Guernsey's environmental committee.
Additionally, it has been advised that the island invest in wind power and boost solar energy production.
According to Lindsay De Sausmarez, deputy chair of the Environment and Infrastructure (Eandamp;I) Committee, consumers are unlikely to experience lower bills in the near future.
An estimated £1.7bn will be needed to operate the Electricity Strategy through 2050.
This is anticipated to be funded by a combination of public and private funds.
In the short to medium term, we do need to brace ourselves for the possibility that electricity prices will rise initially before declining later, according to Mrs. De Sausmarez.
"Our plan essentially accomplishes all the goals in the most efficient manner at the lowest cost, and it gives us the greatest flexibility, supply security, and resilience. ".
Currently, an undersea cable from France that travels via Jersey supplies 93 percent of the island's energy needs.
Only 60 MW can be delivered to Guernsey via that cable; when the island requires more, the diesel generators at the power plant in the Vale are used.
According to the States, the remaining local supply "consists primarily of diesel power generation and a modest level of approximately 350kW of distributed solar photovoltaic.".
E&I has advised the States to look into producing 10MW of solar energy and 65MW of electricity using wind power in addition to the new cable.
The unfortunate thing about that scenario is that it is the most expensive to consumers in the long run, according to Mrs. De Sausmarez, "If the States doesn't provide strategic direction, or support pathway D then Guernsey Electricity will have to assume we are following the status quo. ".
There are six options available to the States for supplying Guernsey's energy requirements through the year 2050.
Pathway A, which is said to be the most expensive at about £1 point 9 billion, entails maintaining the current cable to France via Jersey and enhancing the diesel generators at the power plant of Guernsey Electricity.
Pathway B, which aims to achieve greater energy independence, entails producing electricity on-island using solar and wind energy.
Pathway C is referred to as "renewables first," and it entails maintaining the current cable connection with France via Jersey while boosting the volume of electricity generated locally from renewable energy sources like solar and wind.
E&I prefers Pathway D, which includes investigating wind and solar power generation while also constructing a cable that runs directly to France.
Pathway E calls for the construction of a new cable to France as well as increased solar energy production without wind power.
Pathway F involves investing in cutting-edge technologies alongside those that have been shown to be commercially viable, such as solar and wind, in order to expand the economy through the sale of electricity produced using renewable resources.

The person in charge of this new strategy is warning you not to anticipate a decrease in your bills in the near future, but rather an increase.
E&I is well aware that selling this message during a cost-of-living crisis will be challenging, especially given the estimated costs to the public purse of £1.7 billion by the year 2050.
The challenge in promoting this policy to political colleagues will be highlighting the additional costs of delaying a decision at a time when the message from the purse holders is relentlessly focused on fiscal restraint.
However, this is a high-level strategic policy that instead of immediately committing the States to significant amounts of spending, it opens the door to private investment, new jobs, and new industries—things that the States as a whole are typically very welcoming of.
Although the message is that the funding doesn't have to come from the United States, it is a given that some politicians will be turned off by the cost.
