Renewable Energy

get_renewable_energy

Read-onlyIdempotent

Use this when the user asks about renewable energy for a data center (execute_plan covers renewables plus siting): siting a renewable-powered data center, sizing a PPA, reading one US state's utility-scale fuel mix, or assessing RE100/24-7-CFE feasibility. Example: "What is Texas wind+solar capacity and how much utility-scale solar is operating today?" — get_renewable_energy energy_type=solar state=TX. Params: energy_type one of "solar" | "wind" | "combined" (omit for all); state 2-letter US code (e.g. TX, VA, AZ); lat+lon (optional) for the nearest projects within 50mi. Returns: {capacity_mw_total, by_fuel: {solar_utility, solar_rooftop, wind_onshore, wind_offshore}, capacity_factor_pct, top_projects[{name, mw, operator, cod}], state_rps_target_pct, source: "EIA-860 + state RPS"}. Do NOT use for live grid generation (use get_grid_data) or non-US (use get_grid_scoreboard for EU/UK/AU/TW). Give state or lat/lon (decimal degrees); energy_type narrows. Empty = no installations there: widen to the state.

Input Schema

Name	Required	Description
`lat`	No	Optional latitude in decimal degrees (-90 to 90) to find nearest projects within 50mi
`lng`	No	Alias for lon — either name works
`lon`	No	Optional longitude in decimal degrees (-180 to 180) to find nearest projects within 50mi
`state`	No	US state abbreviation, e.g. TX, VA, AZ
`mpp_pay`	No	Per-call payment quote (Stripe MPP): true returns a signed payment challenge instead of the free preview; no money moves. Set it only after your human has explicitly approved paying for this call.
`latitude`	No	Alias for lat — either name works
`longitude`	No	Alias for lon — either name works
`energy_type`	No	Renewable type: "solar", "wind", or "combined"; omit for all
`mpp_credential`	No	Per-call payment (Stripe MPP): the Shared Payment Token for challenges[0]; pays that challenge for this one call. Send it only with your human's explicit approval of the charge.

A4.7/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral details beyond annotations: the return structure, data source, and what an empty result means. It omits payment/credential behavior, but that is documented in the schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the use case and exclusions, then provides an example, parameter summary, return shape, and fallback behavior. Despite being dense, every sentence adds operational value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the 9-parameter schema, annotations, and existing output schema, the description supplies enough context for correct invocation: when to use it, alternatives to avoid, parameter guidance, return shape, and empty-result handling. No critical behavioral or selection information is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3; the description still adds meaningful selection guidance by explaining that energy_type narrows results, state or lat/lon should be supplied, and lat/lon finds projects within 50 miles. It does not document the mpp_pay or mpp_credential parameters, but their schema descriptions are complete.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific capability: renewable-energy data for data-center use cases, including siting, PPAs, state fuel mix, and RE100/24-7-CFE feasibility. It explicitly distinguishes this tool from execute_plan, get_grid_data, and get_grid_scoreboard, so an agent can select it without opening other schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear when-to-use conditions, a concrete example invocation, and explicit exclusions for live grid generation and non-US regions. It also tells the agent what to provide (state or lat/lon) and how to recover from empty results by widening to the state.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
