The solution is a digital platform that offers a comprehensive toolkit for legislators and advocates to design convincing policy proposals for renewable energy that are politically palatable to a diverse audience.

It features an AI-driven policy impact assessment tool that models the economic, environmental, and social outcomes of proposed policies, tailoring data presentation for bipartisan appeal.

Additionally, it provides an interactive forum for dialogue between stakeholders, including policymakers, industry representatives, and civil society organizations, to co-create balanced policy drafts.

The platform also includes a 'fact-checking' feature to counter misinformation, and a database of successful bipartisan policy case studies from other regions.

By lowering ideological barriers through data-driven insights and fostering collaboration, this platform can streamline policy creation processes and reduce divisiveness.

It provides a structured approach to developing policies that are economically savvy and environmentally conscious, thus aligning varied political interests.

Technologically, the platform leverages existing AI technologies for policy modeling and natural language processing for stakeholder dialogue facilitation.

Costs are manageable with a focus on software development and cloud-based deployment.

While competition exists from advocacy groups, no comprehensive digital tool offering this level of integrated service is yet on the market.

The regulatory environment offers minimal barriers as this is a policy advocacy tool rather than a policy implementer.
